Paper Abstract

We describe a transmission video processing microscope that uses a temporary hologram recorded in real time to provide phase-conjugate illumination of phase and mixed phase and absorption objects. It uses the aberration-removal capabilities of phase conjugation to (1) produce phase contrast in phase objects, (2) make motion in phase objects visible by creating contrast only for moving elements, and (3) eliminate phase background due to an embedding medium or to phase-modulating structures in absorbing (intensity) objects.
