Tissue scattering has a significant effect on the image resolution and light collection efficiency in confocal microscopy. The dual-axes (DA) confocal architecture has many advantages including high axial resolution with low numerical aperture lenses and long working distance for use in vivo as a microendoscope. In addition, less scattered light along the illumination path may be collected and introduced as noise. In this paper, we use Monte Carlo tissue scattering simulations to compare the dual-axes and conventional single-axis (SA) configurations. Simulation results show that the axial response for the dual axes configuration varies with pinhole size and optical thickness of scattering media in a way that differs from the single axis architecture. The DA configuration is able to filter out efficiently multiply-scattered photons and out-of-focus light, thus allowing imaging with greater tissue penetration depths to provide vertical cross-sectional images, which has significant implications for in vivo imaging.

Many optical measurements that are subject to high levels of background illumination rely on phase sensitive lock-in detection to extract the useful signal. If modulation is applied to the portion of the signal that contains information, lock-in detection can perform very narrowband (and hence low noise) detection at frequencies well away from noise sources such as 1/f and instrumental drift. Lock-in detection is therefore used in many optical imaging and measurement techniques, including optical coherence tomography, heterodyne interferometry, optoacoustic tomography and a range of pump-probe techniques. Phase sensitive imaging is generally performed sequentially with a single photodetector and a lock-in amplifier. However, this approach severely limits the rate of multi-dimensional image acquisition. We present a novel linear array chip that can perform phase sensitive, shot-noise limited optical detection in up to 256 parallel channels. This has been achieved by employing four independent wells in each pixel, and massively enhancing the intrinsic well depth to suppress the effect of optical shot noise. Thus the array can reduce the number of dimensions that need to be sequentially scanned and greatly speed up acquisition. Results demonstrating spatial and spectral parallelism in pump-probe experiments are presented where the a. c. amplitude to background ratio approaches 1 part in one million.

Angles of polygon scanners have been measured by using rotary encoders, autocollimators or indexing tables. These methods produce precise angle values but require removal of polygon mirror from its motor. For resolving this inconvenience, we introduce a simple angle measurement method by measuring timing jitters of a scanned beam in the time-domain with a high-speed detector and a digitizer while a polygon scanner is rotating at its full speed. Our setup includes a 635 nm wavelength semiconductor laser, a high-speed photodiode, two lenses, and a high-speed digitizer. A polygon scanner with 12 facets were tested with a rotating frequency of near 350 Hz. To detect the signal of the photodiode, we used a high speed digitizer which has a sampling rate of 2Gs/s with 256MB on-board memory. We obtained repeated pulsed sequential photodiode signals for 12 mirror facets of the scanner. Angle variations and their jitters for 12 scanner mirror facets were successfully calculated from measured data. We have repeated same experiments with a photomultiplier tube and compared results with those measured by a photodiode.

We have applied wide-field digital interferometric techniques to quantitatively image sickle red blood cells (RBCs) [1] in a noncontact label-free manner, and measure the nanometer-scale fluctuations in their thickness as an indication of their stiffness. The technique can simultaneously measure the fluctuations for multiple spatial points on the RBC and thus yields a map describing the stiffness of each RBC in the field of view. Using this map, the local rigidity regions of the RBC are evaluated quantitatively. Since wide-field digital interferometry is a quantitative holographic imaging technique rather than one-point measurement, it can be used to simultaneously evaluate cell transverse morphology plus thickness in addition to its stiffness profile. Using this technique, we examine the morphology and dynamics of RBCs from individuals who suffer from sickle cell disease, and find that the sickle RBCs are significantly stiffer than healthy RBCs. Furthermore, we show that the technique is sensitive enough to distinguish various classes of sickle RBCs, including sickle RBCs with visibly-normal morphology, compared to the stiffer crescent-shaped sickle RBCs.

Structured-illumination microscopy (SIM) is an efficacious tool to decrease the contribution of the out-of-focus light to images of specimens. However, in SIM, the frequency of the spatial modulation applied to specimens should be adjustable according to the optical properties of the specimens to reach the optimal contrasts. Hence, a common theme in SIM is how the flexibility and quality of modulations at different frequencies can be improved. Digital scanned laser light-sheet microscopy with structured illumination (DSLM-SI) has been the most flexible means for generating modulation and optical sectioning. The complexity of synchronization between the temporal modulation and the beam scanning makes it hard to use and less stable;it also takes more time to acquire images for one plane than selective plane illumination microscopy (SPIM). In this report, we present a recent effort to use a spatial light modulator (SLM) to provide spatial modulation in SPIM. With the SLM, both of the frequency and phase of lateral modulation can be changed rapidly;moreover, this SLM-based SPIM can achieve fast imaging without mechanical moving parts.

Multi-modal correlative microscopy allows combining the strengths of several imaging techniques to provide unique contrast. However it is not always straightforward to setup instruments for such customized experiments, as most microscope manufacturers use their own proprietary software, with limited or no capability to interface with other instruments - this makes correlation of the multi-modal data extremely challenging. We introduce a new software tool for simultaneous use of a STimulated Emission Depletion (STED) microscope with an Atomic Force Microscope (AFM). In our experiments, a Leica TCS STED commercial super-resolution microscope, together with an Agilent 5500ilm AFM microscope was used. With our software, it is possible to synchronize the data acquisition between the STED and AFM instruments, as well as to perform automatic registration of the AFM images with the super-resolution STED images. The software was realized in LabVIEW;the registration part was also implemented as an imageJ script. The synchronization was realized by controlling simple trigger signals, also available in the commercial STED microscope, with a low-cost National Instruments USB-6501 digital I/O card. The registration was based on detecting the positions of the AFM tip inside the STED field-of-view, which were then used as registration landmarks. The registration should work on any STED and tip-scanning AFM microscope combination, at nanometer-scale precision. Our STED-AFM correlation method has been tested with a variety of nanoparticle and fixed cell samples. The software will be released under BSD open-source license.

In-vivo microscopic long term time-lapse studies require controlled imaging conditions to preserve sample viability. Therefore it is crucial to meet specific exposure conditions as these may limit the applicability of established techniques. In this work we demonstrate the use of third harmonic generation (THG) microscopy for long term time-lapse three-dimensional studies (4D) in living Caenorhabditis elegans embryos employing a 1550 nm femtosecond fiber laser. We take advantage of the fact that THG only requires the existence of interfaces to generate signal or a change in the refractive index or in the chi(3) nonlinear coefficient, therefore no markers are required. In addition, by using this wavelength the emitted THG signal is generated at visible wavelengths (516 nm) enabling the use of standard collection optics and detectors operating near their maximum efficiency. This enables the reduction of the incident light intensity at the sample plane allowing to image the sample for several hours. THG signal is obtained through all embryo development stages, providing different tissue/structure information. By means of control samples, we demonstrate that the expected water absorption at this wavelength does not severely compromise sample viability. Certainly, this technique reduces the complexity of sample preparation (i.e. genetic modification) required by established linear and nonlinear fluorescence based techniques. We demonstrate the non-invasiveness, reduced specimen interference, and strong potential of this particular wavelength to be used to perform long-term 4D recordings.

The simultaneous manipulation and observation of morphological features of single living cells along with the recording of functional changes related to cellular metabolism, interaction and communication in real time are of growing interest. With the advent of atomic force microscopy (AFM) structural studies of native cells became possible which in combination with adequate light microscopy give a much better resolution than light microscopy alone. However, the motion of the cell, the softness of the cell membrane and the two-dimensional growth of cells in culture limit applicability and resolution of this technique. A good mechanical fixation of living cells in a structure could be achieved by embedding cells into partially covered grooves produced in Si/SiO2. However, for additionally optical microscopy studies a transparent material is essential. In this study we present the fabrication of different transparent three-dimensional structures in a three-layer system (Si3N4, SiO2, Si3N4) on quartz specially sized for the trapping of living neural cells under physiological conditions. For the fabrication of the structures we utilized a combination of e-beam lithography (EBL), laser ablation, reactive ion beam etching (RIBE) and different wet etching techniques. The structures consist of a nano-net of Si3N4 covering a micro-cavity in SiO2 confining enough to prevent the cell body from escaping, but not so constraining that it hinders normal growth and development. Another type of presented structures consists of cavities which are connected by covered micro-channels, hence, an observation of cell-cell interactions is also possible. Advantages of these microstructures are the trapping of cells, the stabilization of the cell membrane and the precise placement of the cells for a multitude of biological investigations.

With the advent of laser scanning confocal and multiphoton microscopy, 3D life tissue characterization has been rendered possible. This involves the restoration of thick section images (in the depth range of 100 microns) of biological samples. In contrast to thin samples new effects become important when imaging thick samples: Because of changes of the refractive index across the specimen or the embedding medium, strong (> 1 micron) focal shifts and spherical aberration occur and scattering effects get more prominent. For tissue mapping it is essential to correct for such aberrations and distortion effects. In this paper. Re propose a calibration framework, which allows us to determine thick section focal shifts and spherical aberrations in a one-step-procedure, Gradients in the focal shift induce a scaling in the Z-direction of the observed sample. A second effect arises with depth-dependent spherical aberration. We model our microscope as a linear-shift-NON-invariant system (LSNI) where multiple depth classes are assigned distinct point spread functions (PSFs). We measure these two effects in a 3D sample of randomly distributed fluorescent focal check beads. The beads are embedded in gelatine, a medium with high resemblance to real biological tissue. The PSF is approximated by a mathematical parametric model. While estimating the parameters of the PSF with object-constrained deconvolution, we track depth dependent changes of the observed bead diameter. This allows us to determine the gradient of the focal shift across a thick section. By numerical integration along the optical axis we obtain the focal shift values as a function of sample depth. In the end, these values will be applied as a correction to compensate depth distortions in the tissue images.

The study of the internal structures of specimens has a great importance in life and materials sciences. The principle of optical diffraction tomography (ODT) consists in recording the complex wave diffracted by an object, while changing the k vector of the illuminating wave. This way, the frequency domain of the specimen is scanned, allowing reconstructing the scattering potential of the sample in the spatial domain. This work presents a method for sub-micron tomographic imaging using multiple wavelengths in digital holographic microscopy. This method is based on the recording at different wavelengths equally separated in the k-domain, of the interference between an off-axis reference wave and an object wave reflected by a microscopic specimen and magnified by a microscope objective. A charged coupled device (CCD) camera records consecutively the holograms, which are then numerically reconstructed following the convolution formulation to obtain each corresponding complex object wavefronts. Their relative phases are adjusted to be equal in a given plane of interest and the resulting complex wavefronts are summed. The result of this operation is a constructive addition of complex waves in the selected plane and a destructive one in the others. Tomography is thus obtained by the attenuation of the amplitude out of the plane of interest. Numerical variation of the plane of interest enables to scan the object in depth. For the presented simulations and experiments, twenty wavelengths are used in the 480-700 nm range. The result is a sectioning of the object in slices of 725 nm thick.
