PLoS ONE, Vol 12, Iss 2, p e0171228 (2017)
We present a new technique for quantitative phase and amplitude microscopy from a single color image with coded illumination. Our system consists of a commercial brightfield microscope with one hardware modification-an inexpensive 3D printed condense

We demonstrate the design and application of an add-on device for improving the diagnostic and research capabilities of CellScope--a low-cost, smartphone-based point-of-care microscope. We replace the single LED illumination of the original CellScope

The human mammary gland is a complex and heterogeneous organ, where the interactions between mammary epithelial cells (MEC) and stromal fibroblasts are known to regulate normal biology and tumorigenesis. We aimed to longitudinally evaluate morphology

We demonstrate multi-frame motion deblurring for gigapixel wide-field fluorescence microscopy using fast slide scanning with coded illumination. Our method illuminates the sample with multiple pulses within each exposure, in order to introduce struct

Maintaining an in-focus image over long time scales is an essential and non-trivial task for a variety of microscopic imaging applications. Here, we present an autofocusing method that is inexpensive, fast, and robust. It requires only the addition o

Fourier Ptychographic Microscopy (FPM) and Differential Phase Contrast (DPC) are quantitative phase imaging (QPI) methods that recover the complex transmittance function of a sample through coded illumination measurements and phase retrieval optimiza

Fourier ptychography captures intensity images with varying source patterns (illumination angles) in order to computationally reconstruct large space-bandwidth-product images. Accurate knowledge of the illumination angles is necessary for good image

We propose an extension of coded illumination design for motion deblurring to multiframe imaging, where a large field-of-view sample is recovered from many motion-blurred measurements captured while scanning the sample continuously under coded illumi

We demonstrate an inexpensive programmable color LED array illuminator with 0.98 numerical aperture (NA), coupled with an auto-calibration procedure, to enable a simple and efficient setup for high-angle Fourier Ptychography in a commercial microscop

We present a quantitative phase imaging method, based on Differential Phase Contrast (DPC), that recovers both the complex-field of a weak object and the spatially-varying pupil functions (aberrations) of the optical system.
