Paper Abstract

A method of optical pseudo-color representation is introduced for distinguishing height distribution of a solid object, flow velocity distribution of fluid and so on. First, a photograph is taken in a proper way so that each part of it posesses a bandpass spatial power spectrum whose center frequency represents height or flow velocity at the corresponding part of the object. Then the "frequency-coded" transparency is converted to colored image by a coherent optical processor with white light illumination.
