Abstract
An adaptive correlator system is presented that uses a bacteriorhodops in film as the active holographic material. Because M-type holography with bacteriorhodopsin films is used, the TV frame rate is met at fair ly low intensities. No limitations arising from the heterodyne operati on of the dual-axis joint-Fourier-transform correlator were observed. The system's capability to monitor autonomously the speed of an object moving randomly in the whole viewing field of a video camera is demon strated.
