Paper Abstract

We describe a real-time laser holographic microscope which uses a photorefractive hologram and digital signal processing. The new microscope produces high-contrast images ofeven weak phase subjects. A pSeUdO-three-dimensiOnal image type is produced which shows phase gradients like those of"modulation contrast" or "differential interference contrast" Mother image type shows phase retardation in a more direct way, as in conventional "phase contrast." Still another type shows images of moving phase elements in a field while rejecting stationary ones.
