In this study, we developed a dark-field illuminated reflectance fiber-optic microscope (DRFM) along with an algorithm for l(1)-norm minimization of fiber bundle image to provide intrinsic endoscopic imaging with cellular resolution. To suppress specular reflection from fiber bundle facets, we adopted a dark-field configuration. To remove the honeycomb pattern of fiber bundle while preserve image resolution and contrast, we chose to minimize the image l(1) norm using iterative shrinkage thresholding (IST) algorithm.

Traditional laser scanning microscopes require complex control systems to synchronize and control image acquisition. The control system is especially cumbersome in the multimodal laser scanning microscope. We have developed a novel multimodal laser scanning microscope control system based on a National Instruments multifunction data acquisition device (DAQ), which serves as both a data acquisition device and a programmable signal generator. The novel control system is low-cost and easy-to-build, with all components off-the-shelf. We have applied the control system in a multimodal laser scanning microscope. The control system has not only significantly decreased the complexity of the microscope, but also increased the system flexibility. We have demonstrated that the system can be easily customized for various applications.

Quantitative phase imaging with digital holographic microscopy (DHM) allows label-free imaging of tissue sections and quantification of the spatial refractive index distribution, which is of interest for applications in digital pathology. We show that DHM allows quantitative imaging of different layers in unstained tissue samples by detection of refractive index changes. In addition, we evaluate the automated refocussing feature of DHM for application on dissected tissues and could achieve highly reproducible holographic autofocusing for unstained and moderately stained samples. Finally, it is demonstrated that in human ulcerative colitis patients the average tissue refractive index is reduced significantly in all parts of the inflamed colonic wall in comparison to patients in remission.

Knowledge of prior sample information, such as a refractive index (RI) map, can be used to improve image formation models enabling more accurate three-dimensional (3D) restoration in fluorescence microscopy. RI is an indicator of cell composition and structure that allows a more comprehensive representation of the 3D structure of a specimen than fluorescence alone. Due to the integral nature of sample phase, the challenge to compute the RI map is to decouple RI and thickness. Our work investigates the feasibility of determining RI of a specimen from differential interference contrast (DIC) microscopy data acquired by using different wavelengths in illumination. This spectral diversity in the data is exploited to determine sample thickness and RI. Results from simulated and experimental data of polystyrene bead samples are presented to analyze this approach. Phase images were estimated from the DIC data using an alternating minimization algorithm. This study shows that the maximum estimated phase delay is accurate within approximately 7 percent error relative to the 2D phase model. The sensitivity of this integrated approach allows RI to be computed within approximately 0.4 percent error relative to values from the literature.

This paper introduces a stereoscopic video imaging modality based on a transparent rotating deflector (TRD). Sequential two- dimensional (2D) left and right images were obtained by rotating the TRD on a stepping motor synchronized with a complementary metal-oxide semiconductor camera, and the components of the imaging modality were controlled through general purpose input/output ports using a microcontroller unit. In this research, live stereoscopic videos were visualized on a personal computer by both active shutter 3D and passive polarization 3D methods. The imaging modality was characterized by evaluating the stereoscopic video image generation, rotation characteristics of the TRD. The level of 3D conception was estimated in terms of simplified human stereovision. The results show that single-channel stereoscopic video imaging modality has the potential to become an economical compact stereoscopic device as the system components are amenable to miniaturization;and could be applied in a wide variety of fields.

Despite imaging systems that scan a single-element benefit from mature technology, they suffer from acquisition times linearly proportional to the spatial resolution. A promising option is to use a single-pixel system that benefits from data collection strategies based on compressive sampling. Single-pixel systems also offer the possibility to use dedicated sensors such as a fiber spectrometer for multispectral imaging or a distribution of photodiodes for 3D imaging. The image is obtained by lighting the scene with microstructured masks implemented onto a programmable spatial light modulator. The masks are used as generalized measurement modes where the object information is expressed and the image is recovered through algebraic optimization. The fundamental reason why the bucket detection strategy can outperform conventional optical array detection is the use of a single channel detector that simultaneously integrates all the photons transmitted through the patterned scene. Spatial frequencies that are not transmitted through this low-quality optics are demonstrated to be present in the retrieved image. Our work makes two specific contributions within the field of single-pixel imaging through patterned illumination. First, we demonstrate that single-pixel imaging improves the resolution of conventional imaging systems overcoming the Rayleigh criterion. An analysis of resolution using a low NA microscope objective for imaging at a CCD camera shows that single-pixel cameras are not limited at all by the optical quality of the collection optics. Second, we experimentally demonstrate the capability of our technique to properly recover an image even when an optical diffuser is located in between the sample and the bucket detector.

Fast beam-scanning non-linear optical microscopy, coupled with fast (8 MHz) polarization modulation and analytical modeling have enabled simultaneous nonlinear optical Stokes ellipsometry (NOSE) and linear Stokes ellipsometry imaging at video rate (15 Hz). NOSE enables recovery of the complex-valued Jones tensor that describes the polarization-dependent observables, in contrast to polarimetry, in which the polarization stated of the exciting beam is recorded. Each data acquisition consists of 30 images (10 for each detector, with three detectors operating in parallel), each of which corresponds to polarization-dependent results. processing of this image set by linear fitting contracts down each set of 10 images to a set of 5 parameters for each detector in second harmonic generation (SHG) and three parameters for the transmittance of the fundamental laser beam. Using these parameters, it is possible to recover the Jones tensor elements of the sample at video rate. Video rate imaging is enabled by performing synchronous digitization (SD), in which a PCIe digital oscilloscope card is synchronized to the laser (the laser is the master clock.) Fast polarization modulation was achieved by modulating an electro-optic modulator synchronously with the laser and digitizer, with a simple sine-wave at 1/10th the period of the laser, producing a repeating pattern of 10 polarization states. This approach was validated using Z-cut quartz, and NOSE microscopy was performed for micro-crystals of naproxen.

We have developed a cellular resolution imaging modality, Gabor-Domain Optical Coherence microscopy, which combines the high lateral resolution of confocal microscopy with the high sectioning capability of optical coherence tomography to image deep layers in tissues with high-contrast and volumetric resolution of 2 mu m. A novelty of the custom microscope is the biomimetics that incorporates a liquid lens, as in whales's eyes, for robust and rapid acquisition of volumetric imaging of deep layers in tissue down to 2 mm, thus overcoming the tradeoff between lateral resolution and depth of focus. The system incorporates a handheld scanning optical imaging head and fits on a movable cart that offers the flexibility in different biomedical applications and clinical settings, including ophthalmology. In the later, the microscope has successfully revealed micro-structures within the cornea and in particular the endothelial cells micro-environment, an important step in understanding the mechanisms of Fuchs' dystrophy, a leading cause of the loss of corneal transparency. Also, the system was able to provide high definition of the edge of soft contact lenses, which is important for the fitting of the lens and the comfort of the patient. Overall, the imaging modality provides the opportunity to observe the three-dimensional features of different structures with micrometer resolution, which opens a wide range of future applications.

We present a versatile fluorescence microscope, built by complementing a conventional fluorescence microscope with a digital micro-mirror device (DMD) in the illumination path. Arbitrary patterns can be created on the DMD and projected onto the sample. This patterned illumination can be used to improve lateral and axial resolution over the resolution of a wide-field microscope, as well as to reduce the illumination dose. Different illumination patterns require different reconstruction strategies and result in an image quality similar to confocal or structured illumination microscopy. We focus on the optical design and characterization of a DMD-based microscope. Estimation of the optical quality of the microscope has been carried out by measuring the modulation transfer function from edge profiles. We have obtained optically sectioned images by applying multi-spot illumination patterns followed by digital pinholing. The sectioning capabilities of our DMD-based microscope were estimated from the dependence of the signal-to-background and signal-to-noise ratios on the pitch of the projected multi-spot patterns and the size of the digital pinhole. In addition, we provide an outlook on the use of pseudo-random illumination patterns for achieving both sectioning and resolution enhancement.

We demonstrate 3D microscope imaging using computational optical sectioning microscopy (COSM) with an engineered point-spread function (PSF) robust to depth-induced spherical aberration (SA). Earlier we demonstrated that wavefront encoding (WFE) using a squared cubic (SQUBIC) phase mask reduces the PSF depth-variance in the presence of SA and that space-invariant (SI) restoration of simulated images using a single WFE-PSF does not lead to artifacts as in the conventional case. In this study, we show experimental verification of our WFE COSM approach. The WFE system used is a commercial microscope with a modified side port imaging path, where a spatial light modulator projects the SQUBIC phase mask on the back focal plane of the imaging lens. High resolution images of a test sample with 6 mu m in diameter microspheres embedded in UV-cured optical cement (RI = 1.47) were captured using both the engineered and the conventional imaging paths of the system. The acquired images were restored using a regularized SI expectation maximization algorithm based on Tikhonov-Miller regularization with a roughness penalty. A comparative study quantified in terms of the correlation coefficients between the XZ medial sections of the restored images, from experimental data, shows an 11% reduction in depth sensitivity in the SQUBIC system compared to the conventional system.
