Lung imaging, visualization and measurement of alveolar volume has great importance in determining lung health. However, the heterogeneity of lung tissue complicates this task. In this paper multi angle Optical Coherence Tomography (OCT) is used to overcome this problem. One of the limitations of utilizing OCT in lung is the speckle noise and artifacts that originate from the refraction at the tissue-air interface inside the lung. Multi angle view of lung using OCT is incoherent summation of multiple angle-diverse images. Utilizing image registration of multi angle OCT scans of the lung helps reduce the speckle noise and refraction artifacts. This technique helps extract more information from the images which improves visualization and the ability to measure the geometry of alveoli. The other difficulty of utilizing OCT is interpreting the images due to the low numerical aperture (NA) on the OCT. The multi angle view of the lung increases NA, which increase the imaging resolution through synthetic aperture imaging. In this paper inflated excised lung tissue and lung phantom are presented.

When confocal depth stacks are taken, the collected signal (normally the fluorescence signal), decays dependent of the depth of the confocal slice in the turbid medium. This decay is caused by scattering and absorption of the exciting light and of the fluorescence light. As the attenuation parameters, i.e. scattering and absorption coefficients, are normally unknown when observing a new sample, a method is proposed to compensate for the attenuation of the involved light by correcting the fluorescence signal using the attenuation behavior of the sample measured directly on the spot where the fluorescence stack is taken. The method works without any a priori knowledge about the optical properties of the sample. Using this self-reference technique, a confocal fluorescence depth stack can be created where the signal intensity is not dependent on the scattering and absorption caused intensity decay. The proposed method is tested on fluorescent beads embedded in scattering and absorbing hydrogel phantoms.

In fluorescence microscopy, one can distinguish two kinds of imaging approaches, wide field and raster scan microscopy, differing by their excitation and detection scheme. In both imaging modalities the acquisition is independent of the information content of the image. Rather, the number of acquisitions N, is imposed by the Nyquist-Shannon theorem. However, in practice, many biological images are compressible (or, equivalently here, sparse), meaning that they depend on a number of degrees of freedom K that is smaller that their size N. Recently, the mathematical theory of compressed sensing (CS) has shown how the sensing modality could take advantage of the image sparsity to reconstruct images with no loss of information while largely reducing the number M of acquisition. Here we present a novel fluorescence microscope designed along the principles of CS. It uses a spatial light modulator (DMD) to create structured wide field excitation patterns and a sensitive point detector to measure the emitted fluorescence. On sparse fluorescent samples, we could achieve compression ratio N/M of up to 64, meaning that an image can be reconstructed with a number of measurements of only 1.5 % of its pixel number. Furthemore, we extend our CS acquisition scheme to an hyperspectral imaging system.

Accurate control over the phase and amplitude modulation in an adaptive microscope is essential to the quality of aberration correction that can be achieved. In this paper we present a robust and compact method for characterising such amplitude and phase modulation in the pupil plane of the focussing objective. This method, based on phase diversity, permits calibrating the microscope as a whole and thus avoids errors in the alignment of the wavefront shaping device after calibration and the resulting imprecision in the induced modulation: by acquiring three 2D images of the point spread function at different distances from the focal plane, we show that the electric field distribution at the pupil plane can be retrieved using an iterative algorithm. We have applied this technique to the characterisation of the phase modulation induced by a deformable mirror when conjugated with the entrance pupil of different objectives, which permits accurate evaluation of the performance of the mirror for subsequent aberration correction.

Digital holographic microscopy (DHM) has been gaining interest from cell biology community because of its label free nature and quantitative phase signal output. Besides, fast shutter time, image reconstruction by numerical propagation of the wave fields, and numerical compensation of the aberrations are other intrinsic advantages of this technique that can be explored for harsh imaging conditions. In the frame of this work, a transmission type DHM is developed with a decoupled epifluorescence microscopy mode for cytomorphological monitoring under zero gravity and hyper gravity. With the implemented automatic post processing routines, real time observation of the cell morphology is proven to be feasible under the influence of mechanical disturbances of zero gravity platforms. Post processing of holograms is composed from dynamic numerical compensation of holograms, robust autofocusing and phase image registration. Experiments on live myoblast cells are carried out on two different platforms;random positioning machine (RPM), a ground base microgravity simulation platform, and parabolic flight campaign (PFC), a fixed wing plane flight providing short durations of alternating gravity conditions. Results show clear perinuclear phase increase. During seconds scale microgravity exposure, measurable scale morphological modifications are observed with the accumulated effect of repetitive exposures and short breaks.

Point spread function engineering with a double helix (DH) phase mask has been recently used in a joint computational-optical approach for the determination of depth and intensity information from fluorescence images. In this study, theoretically determined DH-PSFs computed from a model that incorporates different amounts of depth-induced spherical aberration (SA) due to refractive-index mismatch in the three-dimensional imaging layers, are evaluated through a comparison to empirically determined DH-PSFs measured from quantum dots. The theoretically-determined DH-PSFs show a trend that captures the main effects observed in the empirically-determined DH-PSFs. Calibration curves computed from these DH-PSFs show that SA slows down the rate of rotation observed in a DH-PSF which results in: 1) an extended range of rotation;and 2) asymmetric rotation ranges as the focus is moved in opposite directions. Thus, for accurate particle localization different calibration curves need to be known for different amounts of SA. Results also show that the DH-PSF is less sensitive to SA than the conventional PSF. Based on this result, it is expected that fewer depth-variant (DV) DH-PSFs will be required for 3D computational microscopy imaging in the presence of SA compared to the required number of conventional DV PSFs.

The performance of imaging devices such as linear and nonlinear microscopes (NLM) can be limited by the optical properties of the imaged sample. Such an important aspect has already been described using theoretical models due to the difficulties of implementing a direct wavefront sensing scheme. However, these only stand for simple interfaces and cannot be generalized to biological samples given its structural complexity. This has leaded to the development of sensor-less adaptive optics (AO) implementations. In this approach, aberrations are iteratively corrected trough an image related parameter (aberrations are not measured), being prone of causing sample damage. In this work, we perform a practical implementation of a Shack-Hartman wavefront sensor to compensate for sample induced aberrations, demonstrating its applicability in linear and NLM. We perform an extensive analysis of wavefront distortion effects through different depths employing phantom samples. Aberration effects originated by the refractive index mismatch and depth are quantified using the linear and nonlinear guide-star concept. More over we analyze off-axis aberrations in NLM, an important aspect that is commonly overlooked. In this case spherical aberration behaves similarly to the wavefront error compared with the on-axis case. Finally we give examples of aberration compensation using epi-fluorescence and nonlinear microscopy.

A phase shifting differential interference contrast (DIC) microscope, which provides quantitative phase information and is capable of imaging at video rates, has been constructed. Using a combination of phase shifting and bi-directional shear, the microscope captures a series of eight images which are then integrated in Fourier space. In the resultant image the intensity profile linearly maps to the phase differential across the object. The necessary operations are performed by various liquid crystal devices (LCDs) which can operate at high speeds. A set of four liquid crystal prisms shear the beam in both the x and y directions. A liquid crystal bias cell delays the phase between the e- and o-beams providing phase-shifted images. The liquid crystal devices are then synchronized with a CCD camera in order to provide real-time image acquisition. Previous implementation of this microscope utilized Nomarski prisms, a rotation stage and a manually operated Senarmont compensator to perform the necessary operations and was only capable of fixed sample imaging. In the present work, a series of images were taken using both the new LCD prism based microscope and the previously implemented Senarmont compensator based system. A comparison between these images shows that the new system achieves equal and in some cases superior results to that of the old system with the added benefit of real-time imaging.

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.

The electron-multiplying charge-coupled device (EMCCD) is a popular technology for imaging under extremely low light conditions. It has become widely used, for example, in single molecule microscopy experiments where few photons can be detected from the individual molecules of interest. Despite its important role in low light microscopy, however, little has been done in the way of determining how accurately parameters of interest (e. g., location of a single molecule) can be estimated from an image that it produces. Here, we develop the theory for calculating the Fisher information matrix, and hence the Cramer-Rao lower bound-based limit of the accuracy, for estimating parameters from an EMCCD image. An EMCCD operates by amplifying a weak signal that would otherwise be drowned out by the detector's readout noise as in the case of a conventional charge-coupled device (CCD). The signal amplification is a stochastic electron multiplication process, and is modeled here as a geometrically multiplied branching process. In developing our theory, we also introduce a "noise coefficient" which enables the comparison of the Fisher information of different data models via a scalar quantity. This coefficient importantly allows the selection of the best detector (e.g., EMCCD or CCD), based on factors such as the signal level, and regardless of the specific estimation problem at hand. We apply our theory to the problem of localizing a single molecule, and compare the calculated limits of the localization accuracy with the standard deviations of maximum likelihood location estimates obtained from simulated images of a single molecule.
