Paper Abstract

To gain the advantages of both spatial and temporal heterodyne techniques, and to make efficient use of the limited spatio-temporal frequency bandwidth of image detection systems, we propose a novel technique of spatio-temporal heterodyne interferometry using both spatial and temporal carrier frequencies. By means of spatio-temporal frequency multiplexing, the technique enables simultaneous recording of multiple phase objects on a single space-time interferogram.
