Abstract: Multifocal photoacoustic imaging systems and methods that implement an ergodic relay to encode photoacoustic signals detected from a plurality of illuminated optical foci regions.

Abstract: A computer-implemented method (530), system (100, 201) and computer readable medium for generating a slide-free histological image in the form of a reconstructed ultraviolet-based autofluorescence microscopy (UV-AutoM) image from a plurality of speckle-illuminated low-resolution images. A computer implemented method (1150), system (100, 201) and computer readable medium for generating a slide-free histological image in the form of a pseudo-hematoxylin and cosin (H&E) stained image (1120) from a grayscale input image such as a UV-AutoM image or a ultraviolet-based photoacoustic microscopy (UV-PAM) image (1110).

Abstract: Systems and method for high-speed single-pixel quantitative phase contrast optical imaging are provided. This imaging technique can bypass the use of conventional image sensors and their associated speed limitations. The quantitative phase images can be acquired much faster than conventional quantitative phase imaging by a chirped-wavelength-encoding mechanism via wavelength-swept laser sources or optical time-stretch based on optical fibers, without the need for interferometric approaches.
