Coherent holographic image reconstruction by phase transfer (CHIRPT) is an imaging method that permits digital holographic propagation of fluorescent light. The image formation process in CHIRPT is based on illuminating the specimen with a precisely controlled spatio-temporally varying intensity pattern. This pattern is formed by focusing a spatially coherent illumination beam to a line focus on a spinning modulation mask, and image relaying the mask plane to the focal plane of an objective lens. Deviations from the designed spatio-temporal illumination pattern due to imperfect mounting of the circular modulation mask onto the rotation motor induce aberrations in the recovered image. Here we show that these aberrations can be measured and removed non-iteratively by measuring the disk aberration phase externally. We also demonstrate measurement and correction of systematic optical aberrations in the CHIRPT microscope.

Optical projection tomography (OPT) requires a large depth of field (DOF) of a low numerical aperture (NA) lens resulting in low resolution. However, DOF of a high NA objective can be extended by scanning the focal plane through the sample. This extended DOF image is called pseudoprojection, which is used by optical projection tomographic microscope (OPTM) for tomographic reconstruction. The advantage of OPTM is the acquisition of relatively high resolution and large depth of field concurrently. This method requires the working distance of the lens to be larger than the size of the sample, so proper lens should be chosen for samples of different sizes. In this paper, we imaged hematoxylin stained muntjac cells inside capillary tube with two different sizes. Two objective lenses with different NA are used for these two tubes. Experimental results show that resolution improves over 10 times in OPTM compared to conventional OPT, which make it possible for OPTM technique to resolve sub-cellular features for large samples. Therefore, OPTM can be used for 3D histological analysis of hematoxylin & eosin (H&E) stained biopsy specimen with sub-cellular resolution in the future.

In three-dimensional (3D) computational imaging for wide-field microscopy, estimation methods that solve the inverse imaging problem play an important role. The accuracy of the forward model has a significant impact on the complexity of the estimation method and consequently on the accuracy of the estimated intensity. Previous studies have shown that a forward model based on a depth-varying point-spread function (DV-PSF) leads to a substantial improvement in the resulting images because it accounts for depth-induced aberrations present in the imaging system. In this depth-varying (DV) model, the depth-dependent imaging effects are handled using a stratum-based interpolation method defined on discrete, non-overlapping layers or strata along the Z axis. Recently, a new approximation method based on a principle component analysis (PCA) was developed to predict DV-PSFs(1) with improved accuracy over the DV-PSFs predicted by the strata interpolation method of Ref. [11]. In this study, we implemented the PCA-based forward model for DV imaging to further compare the two approaches. DV-PSFs and forward models were computed using both the strata-based and the new PCA-based approximation schemes. Differences are quantified as a function of the approximation, i.e. the number of bases or strata used in each case respectively. A new PCA-based image estimation method was also developed based on the DV expectation maximization (DV-EM) algorithm of Ref. [11]. Preliminary evaluation of the performance of the PCA-based estimation shows promising results and consistency with previous results obtained in previous studies(1).

Recently surgery requires extensive support from imaging technologies in order to increase effectiveness and safety of operations. One of important tasks is to enhance visualisation of quasi-phase (transparent) 3D structures. Those structures are characterized by very low contrast. It makes differentiation of tissues in field of view very hard. For that reason the surgeon may be extremely uncertain during operation. This problem is connected with supporting operations of inner ear during which physician has to perform cuts at specific places of quasi-transparent vellums. Conventionally during such operations medical doctor views the operating field through stereoscopic microscope. In the paper we propose 3D visualization system based on Helmet Mounted Display. Two CCD cameras placed at the output of stereoscopic microscope perform acquisition of stereo pairs of images. The images are processed in real-time with the goal of enhancement of quasi-phase structures. The main task is to create an algorithm that is not sensitive to changes in intensity distribution. The disadvantages of existing algorithms are their lack of adaptation to occurring reflexes and shadows in field of view. The processed images from both left and right channels are overlaid on the actual images exported and displayed at LCD's of Helmet Mounted Display. A physician observes by EMD a stereoscopic image of operating field with indication of the regions of special interest. The authors present the hardware, procedures applied and initial results of inner ear structure visualization. Several problems connected with processing of stereo-pair images are discussed.

We present a novel Fourier domain method for microscopic imaging - so-called k-microscopy- with lateral resolution independent of the detection numerical aperture. The concept is based on sample illumination by a lateral fringe-pattern of varying spatial frequency, which probes the lateral spatial frequency or k- spectrum of the sample structure. The illumination pattern is realized by interference of two collimated coherent beams. Wavelength tuning is employed for modulation of the fringe spacing. The uniqueness of the proposed system is that a single point detector is sufficient to collect the total light corresponding to a particular position in the sample k-space. By shifting the phase of the interference pattern, we get full access to the complex frequencies. An inverse Fourier transformation of the acquired band in the frequency- or k-space will reconstruct the sample. The resulting lateral resolution will be defined by the temporal coherence length associated with the detected light source spectrum as well as by the illumination angle. The feasibility of the concept has been demonstrated in 1D.

The spatial point spread function is studied for two-photon fluorescence imaging in turbid media. Using a Monte Carlo based model the effects of tissue optical properties on the point spread function, fluorescence generation, and fluorescence collection are studied. The simulated results are compared to measured point spread functions at different depths within a scattering sample. Results indicate that the limiting factor in two-photon imaging is a loss of signal caused by scattering rather than a loss of resolution.

Light-sheet microscopy, it is known as single plane illumination microscope (SPIM), is a fluorescence imaging technique which can avoid phototoxic effects to living cells and gives high contrast and high spatial resolution by optical sectioning with light-sheet illumination in developmental biology. We have been developed a multifunctional light-sheet fluorescence microscopy system with a near infrared femto-second fiber laser, a high sensitive image sensor and a high throughput spectrometer. We performed that multiphoton fluorescence images of a transgenic fish and a mouse embryo were observed on the light-sheet microscope. As the results, two photon images with high contrast and high spatial resolution were successfully obtained in the microscopy system. The system has multimodality, not only mutiphoton fluorescence imaging, but also hyperspectral imaging, which can be applicable to fluorescence unmixing analysis and Raman imaging. It enables to obtain high specific and high throughput molecular imaging in vivo and in vitro.

Time-resolved confocal microscopy is well established to image spectral and spatial properties of samples in biology and material science. Atomic Force microscopy (AFM) in addition enables to investigate properties which are not optically addressable or are hidden by the diffraction limited optical resolution. We present a straight forward combination of single molecule sensitive time-resolved confocal microscopy with different commercially available AFMs. Besides an extra of information about for example a cell surface, the AFM tip can also be used to manipulate the sample on a nanometer scale down to the single molecule level.

In holographic tomography (HT), the 3D refractive index distribution within weakly-scattering, phase-only biological object is retrieved. This key property of the technique is one of its most significant strengths compared to labelling-based methods of cell analysis such as fluorescence microscopy. As a consequence, however, it is required to acquire a set of holograms at several viewing directions, which hinders the measurement speed. In this paper we explore the prospect of multiplexing projections in order to decrease the number of scanning positions required for the full measurements. The presented analysis is based on experimental data acquired in a limited-angle holographic tomography system and emulates the performance of a spatial-light-modulator-based system in which multiple projections may be acquired simultaneously by generating a distribution of multiple point sources in the Fourier plane of the condenser lens. For this reason, the increase in acquisition speed strictly depends on the number of multiplexed holograms and results in decreased reconstruction quality. The performance of the system is demonstrated and analyzed with biological objects - human keratinocyte cells.

We have proposed virtual-phase-conjugation-based optical tomography (VPC-OT) using a virtual phase conjugation technology for single-shot and three-dimensional optical tomography. In VPC-OT, a random-spatial-phase-modulated probe beam is irradiated to the sample to be measured, and the complex amplitude of the signal composed of a superimposition of light reflected from each layer of the sample is measured. A three-dimensional tomogram of intensity and phase is obtained by reproducing the measured complex amplitude using a phase conjugate wave in a virtual optical system built in a computer. At this time, by changing the parameters of the virtual optical system, it becomes possible to obtain information of various tomographic planes from the data obtained with a single measurement. In the ideal virtual phase conjugate reproduction process, free space propagation can be assumed;however, in the actual measurement, due to the distortion of the waves and the surroundings of the sample to be measured, a mismatch will occur in modulation and demodulation, and the separation accuracy between different tomographic planes would be degraded. We perform an experiment to clarify the characteristics of VPC-OT in this situation. In this experiment, three-dimensional optical tomography is performed using an etching glass having a periodic structure of 30 mu m as a sample, and the phase distribution is measured quantitatively. Furthermore, by placing a cover glass in front of the object and performing the same measurement, we discuss the characteristics and performance of VPC-OT when there is an optical distortion around the sample to be measured.
