Abstract

A micro optics of 24 X 24 binary phase-only Fresnel lens array with eight discrete phase levels has been made on a quartz substrate. The diffraction efficiency is about 80%. Being of the functions of beamsplitter and Fourier transformation, it can be used in multiple optical correlator to enlarge the memory capacity for target recognition and to make the system smaller, lighter, inexpensive and good accuracy.
