We present a product-of-convolutions (POC) model for phase microscopy images. The model was designed to simulate phase images of thick heterogeneous transparent objects. The POC approach attempts to capture phase delays along the optical axis by modeling the imaged object as a stack of parallel slices. The product of two-dimensional convolutions between(More)

Spectrally encoded confocal microscopy (SECM) is a high-speed reflectance confocal microscopy technology. SECM utilizes a stationary optical element, a diffraction grating, and a broadband light source to illuminate a line on(More)
Phase microscopy modalities are extensively used to image living transparent biological samples because of their ability to obtain high contrast images without the use of enhancing agents. However when the imaged object is optically thick, that is, when the thickness of the object is larger than the depth of field of the imaging system, the development of(More)
