Adaptive bacteriorhodopsin-based holographic correlator for speed measurement of randomly moving three-dimensional objects.
An adaptive correlator system is presented that uses a bacteriorhodopsin film as the active holographic material. Because M-type holography with bacteriorhodopsin films is used, the TV frame rate is met at fairly low intensities. No limitations arising from the heterodyne operation 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 demonstrated.
