Scanning reflectance confocal microscopy (SRCM) is a flexible technology that provides cellular resolution images of tissue morphology with tailored resolutions and fields of view. However, how accurately an object is represented, in other words its fidelity, is critical in medical imaging and is not represented simply by optical resolution. In this work we characterize the SRCMs fidelity of images derived within turbid media. We present theoretical and experimental results showing the improved fidelity when using modal illumination. We investigated the use of TEM10 illumination and a novel implementation of Nomarski differential-interference-contrast (DIC). Using a repeatable, stable turbid phantom the system fidelity was characterized.

A computed-tomography microscope using a digital spatial light modulator has been developed and has demonstrated cytological and histological three-dimensional (3-D) image acquisition. The system consists of two high NA objective lenses, a Digital Micromirror Device (DMD) placed conjugate to the back pupil plane of the illumination objective, a sample stage, a light source, and a CCD detector. Each DMD micromirror can control the illumination of a specific angle. A single 3-D reconstruction is obtained from parallel ray projections acquired by changing the polar angle of illumination -phi (max) less than or equal to phi less than or equal to phi (max) while holding the azimuthal angle theta constant. The polar angle is limited by the NA of the objective. To compensate for an incompleteness of information due to the limited polar angles, several reconstructions acquired at multiple azimuthal angles are combined to create a final reconstruction. A reconstruction algorithm was developed using simulation software based on the 3-D Radon transformation and 3-D synthetic objects. Microscopic 3-D volume reconstructions of quantitatively absorption-stained cells have been demonstrated. 3-D reconstructed images enables the analysis of cell morphology and tissue architecture, as well as virtual two-dimensional slices with the distance between slices of 0.3 mum.

Recently, it has been demonstrated that sectioning within a turbid media using structured illumination microscopy can be greatly enhanced through the use of a Hilbert transform algorithm. This technique, known as single image structured illumination microscopy (SISIM), provides high quality sectioning even within a strongly refracting/scattering medium, such as tissue. It is found that motion artifacts comprise a large portion of the error in in-vivo imaging. Thus, we expand on the SISIM technique by implementing an image registration algorithm which greatly mitigates motion induced artifacts. Multiple images and movies are developed to demonstrate SISIMs ability to provide real-time, in-vivo imaging of human tissue.

This paper describes the application of a dual-dispersive (DD) coded aperture snapshot spectral imager (CASSI) to fluorescence microscopy. CASSI records an interleaved spatially varying, spectrally filtered map of an object onto a two-dimensional (2D) focal plane. Using a compressive sensing framework, the spectrally encoded 2D scene is reconstructed into a three-dimensional (3D) data cube. CASSI also records a 3D dataset at video rate making it suitable for dynamic cellular imaging. A convex optimization technique combining least squares QR factorization with a total variance constraint is used to reconstruct the image. The system records 32 spectral channels that span the spectral range between 450nm and 750nm with 10nm spectral resolution for any pixel in a 2D image. This paper illustrates the application of CASSI imaging to fluorescence microscopy applications. We report on the reconstruction of fluorescent microspheres used in fluorescence microscopy as calibration standards. images are compared with a multi-spectral confocal system.

We present a multispectral polarimetric imagine, system well suited for complete Mueller matrix microscopy. The source is a spectrally filtered halogen light bulb, and the image is formed on a fast CCD camera The light polarization is modulated before the sample and analyzed after the sample by using nematic liquid crystal modulators.. The whole Mueller matrix image of the sample is typically measured over 5 seconds for a good signal-to-noise ratio. The instrument design, together with an original and easy-to-operate calibration procedure provides a high polarimetric accuracy over wide ranges of wavelengths and magnifications. Mueller polarimetry provides separate images of scalar and vector retardation and dichroism of the sample, together with its depolarizing power, while all these effects do contribute simultaneously to the contrasts observed in standard polarized microsopy. Polarimetric images of several samples, namely an unstained rabbit cornea, a picrosirius red stained hepatic biopsy, and a rat artery specifically stained for collagen III are shown and discussed.

Cryogenic procedures are fundamental tools in modern biology, e. g. for conservation or purification of biological materials. The processes occurring in biological cells and tissues during freezing and thawing are subject to ongoing research. Optimization of cell survival rates demands the development and evaluation of exactly defined temperature profiles. 4D-DMD-microscopy is capable of imaging these highly dynamic processes with high spatial and temporal resolution, utilizing well established staining procedures for differentiating structures of interest.

Digital holographic microscopy (DHM) enables high resolution non-destructive inspection of technical surfaces and minimally-invasive label-free live cell imaging. However, the analysis of confluent cell layers represents a challenge as quantitative DHM phase images in this case do not provide sufficient information for image segmentation, determination of the cellular dry mass or calculation of the cell thickness. We present novel strategies for the analysis of confluent cell layers with quantitative DHM phase contrast utilizing a histogram based-evaluation procedure. The applicability of our approach is illustrated by quantification of drug induced cell morphology changes and it is shown that the method is capable to quantify reliable global morphology changes of confluent cell layers.

We present a programmable array microscope (PAM) which uses a pair of ferroelectric liquid crystal spatial light modulators (FLC SLMs). The system is similar to a confocal imaging system called a direct-view microscope (DVM), in which scanned aperture arrays are used to obtain real-time confocal images. The PAM, unlike the DVM, allows arrays to be scanned electronically rather than mechanically. In our system, one SLM is placed in the source plane of a conventional microscope system;the other is placed in the detector plane. Confocal aperture arrays are displayed and scanned synchronously on the SLMs and confocal imaging results. The resolution is improved when compared to a similar previously presented system which employed a single SLR I. We present axial resolution measurements for a variety of array dimensions and investigate the use of aperture correlation techniques to improve the light throughput in the devices.

Both coherence and polarization play an important role in microscopy. It was long ago established that, in the context of scalar treatments, Kohler and critical illumination produce equivalent coherence functions in an object plane. This paper examines this equivalence in the context of polarization vortex illumination. Using a reversed-wavefront Young interferometer (RWYI), we show measurements of the coherence and correlation properties of the output illumination plane of various illumination systems. We compare the coherence properties of critical and Kohler vortex illumination schemes and look at the effects these properties have in an imaging system.

In 3D wide-field computational microscopy, the image formation process is depth variant due to the refractive index mismatch between the imaging layers. In a previous study, an image estimation method based on a principle component analysis (PCA) model for the representation of the depth varying point spread function (DV-PSF) was presented and demonstrated with noiseless simulations(1). In this study, the performance of the PCA-based DV expectation maximization algorithm (PCA-DVEM) was further evaluated with noisy simulations. Different levels of Poisson noise were used in simulated forward images of a synthetic object computed using theoretically-determined DV-PSFs approximated by the PCA approach. The noise influence on the reconstructed images obtained with PCA-DVEM was evaluated. We found that without regularization, the algorithm performs well when the signal-to-noise ratio (SNR) is 14 dB or higher. The relationship of the number of PCA components, B, to the image reconstruction performance was also investigated on both noiseless and noisy simulated data. In both cases, we found that the number of PCA components has limited effect on the image reconstruction performance for B > 1. To reduce computational complexity while maintaining image estimation performance, B = 2 is suggested for processing experimental data.
