Transient detection microscopy

Abstract

We demonstrate a transient detection microscope (Fig. 1) which preferentially displays the image of any moving objects and suppresses stationary ones. This device does not use any electronics; it is a single-task all-optical analog computer which uses the nonlinear coupling of two optical beams in a photorefractive crystal of barium titanate.
