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.
