We report on a deconvolution method developed in a Bayesian framework for adaptive-optics corrected images of the human retina. The method takes into account the three-dimensional nature of the imaging process;it incorporates a positivity constraint and a regularization metric in order to avoid uncontrolled noise amplification. This regularization metric is designed to simultaneously smooth noise out and preserve edges, while staying convex in order to keep the solution unique. We demonstrate the effectiveness of the method, and in particular of the edge-preserving regularization, on realistic simulated data.

Diffraction tomography (DT) is an established imaging technique for reconstructing the complex-valued refractive index distribution of a weakly scattering 3D sample. Due to experimental difficulties associated with the direct measurement of the phase of an optical wavefield, the effectiveness of DT for optical imaging applications has been limited. A theory of intensity diffraction tomography (I-DT) has been proposed to circumvent this phase retrieval problem. In this work, we review the features of I-DT reconstruction theory that are relevant to optical microscopy. Computer-simulation studies are conducted to investigate the performance of reconstruction algorithms for a proposed I-DT microscope. The effects of data noise are assessed, and statistically optimal reconstruction strategies that employ multiple detector planes are proposed.

Structured illumination microscopy (SIM) is a valuable tool for three-dimensional microscopy and has numerous applications in bioscience. Its success has been limited to static objects, though, as three sequential image acquisitions are required per final processed, focused image. To overcome this problem we have developed a multicolored grid which when used in tandem with a color camera is capable of performing SIM with just a single exposure. images and movies demonstrating optical sectioning of three-dimensional objects are presented, and results of applying color SIM for wide-field focused imaging are compared to those of SIM. From computer modeling and analytical calculations a theoretical estimate of the maximum observable object velocity in both the lateral and axial directions is available, implying that the new method will be capable of imaging a variety of live objects. Sample images of the technique applied to lens paper and a pigeon feather are included to show both advantages and disadvantages of CSIM.

We present a new fluorescence microscopy technique that provides depth discrimination in thick tissue. The technique relies on a simple modification to a conventional wide-field microscope, and consists in illuminating the sample with a sequence of speckle patterns and displaying the RMS or the variance of the resultant sequence of fluorescent images. We demonstrate quasi-confocal optical sectioning with an axial resolution of 5 microns FWHM. The lateral resolution is identical to the widefield microscope, namely 0.6 micron FWHM. images of a mouse brain are compared with standard wide-field images, demonstrating an efficient quasi-sectioning capacity in thick tissue throughout approximatively 100 microns depth. This is achieved because of the high contrast maintained by speckle in a scattering media.

We propose a new technique for obtaining three-dimensional phase distribution on differential interference contrast microscope to modulate relative phase retardation between two shear beams. Using partial coherent theory we extract the phase information from two different retardation images. For the object in a weak phase region, simple formula is derived. The images of nematomorph were obtained in vivo.

The scanning photon microscope technique is a method of microscopic image formation that employs a laser beam focused on a sample, while non-imaging detector receives the scattered light. The scans are achieved by means of a galvanometer based scanning mirror and a motorized micrometer. The system produces images analogous to the scanning electron microscopy with three-dimensional effects of shadowing and reflection. Compared to a conventional wide-field imaging system, the method allows for a greater ease of operation and flexibility, as the image quality is dependent upon the characteristics of the laser beam, rather than imaging optics. The image resolution on the order of a micron is demonstrated. A further gain in terms of resolution and the depth of focus by employment of Bessel rather than Gaussian beams is discussed. Additionally, we used a position-sensitive quadrant photodiode detector to highlight the overall spatial orientation of the imaged surface as well as its roughness. This concept can be useful in many areas, such as coherence imaging and fluorescence.

Recently, stimulated emission depletion microscopy has achieved high resolution in fluorescent imaging. In this paper, we present effects of a pupil filter on the performances of stimulated emission depletion microscopy. In stimulated emission depletion microscopy, a saturated zero-centered spot is usually used to achieve a high lateral resolution. Using a half-coated phase plate, a zero-centered spot was made with a narrow and steep gap at the center. Numerical and experimental results show that by simply inserting a central obstacle as a pupil filter, it is possible to reduce the central gap of the zero-centered spot. However in order to compensate inevitable loss of light, which is blocked by the obstacle, increased laser power is required.

Multi-wavelength phase imaging interferography is a technique that combines phase-shifting interferometry with multiwavelength phase unwrapping. It can be used to obtain phase profile of an object without 2 pi ambiguities inherent to single wavelength phase images. In this technique, a Michelson-type interferometer is illuminated by an LED and the reference mirror is dithered for obtaining interference images at four phase quadratures, which are combined to calculate the phase of the object surface. The 2 pi discontinuities are removed by repeating the experiment using two or three LEDs at different wavelengths, which yields phase images of effective wavelength much longer than the original. The resulting image is a profile of the object surface with a height range of several microns and noise levels of 10's of nm. The technique is applied to imaging of phase profile of microscopic objects. The interferographic images using broadband source are significantly less affected by coherent noise, and there are a number of other advantages, such as lower cost and ease of operation.

Techniques of digital holography are improved in order to obtain high-resolution, high-fidelity images of quantitative phase-contrast microscopy. In particular, the angular spectrum method of calculating the holographic optical field is seen to have several advantages over the more commonly used Fresnel transformation or Huygens convolution method. Spurious noise and interference components can be tightly controlled through the analysis and filtering of the angular spectrum. The reconstruction distance does not have a lower limit and the off-axis angle between the object and reference can be lower than the Fresnel requirement and still be able to cleanly separate out the zero-order background. Holographic phase images are largely immune from the coherent noise common in amplitude images. Together with the use of a miniature pulsed laser, the resulting images have 0.5 mu m diffraction-limited lateral resolution and the phase profile is accurate to about 30 nm of optical path length. SKOV-3 (ovarian cancer cells) and HUVEC (human umbilical vein endothelial cells) are imaged that display intra-cellular and intra-nuclear organelles with clarity and quantitative accuracy. The technique clearly exceeds currently available methods in phase-contrast optical microscopy in the level of resolution and detail, and provides a new modality for imaging morphology of cellular and intracellular structures that is not currently available.

Fluorescence microscopy of live cells is an important tool to investigate cellular trafficking pathways. The existing microscope design is very well suited to image fast moving vesicles, tubules and organelles in one focal plane. More problematic is the imaging of cellular components that move between different focal planes. This is due to the fact that tracking of such cellular components requires that the focal plane of the microscope be changed. This has to be done with a focusing device, which is relatively slow. More importantly, only one focal plane can be imaged at a time. Therefore, while the cell is imaged at one focal plane, important events could be missed at other focal planes. To overcome these shortcomings, we present a modification of the classical microscope design with which two or more focal planes can be imaged simultaneously. In this design, the emission light collected by a single stationary objective lens is split into multiple channels. Light in each channel is focused on a CGD camera by a tube lens. By ensuring that the camera position with respect to the tube lens focal plane position is not the same in any two channels, distinct planes within the specimen can be simultaneously imaged. Here we discuss the implementation of a configuration with which four focal planes can be imaged simultaneously.
