Design and fabrication of highly efficient optical array generator

Abstract

The design of optical array generator is based on the scalar diffraction theory. Optical array diffraction intensity is the same for all diffraction levels. Optical array generator can be modulated by either the amplitude or phase profile, however, phase array generator is done through ion etching. The design and fabrication of highly efficient optical array generator is studied, one and two dimensional optical array generator is designed, which generate 16, 32,64, 256, 1024, 4096 uniform optical arrays separately. The optical array generator has been used in optical pattern recognition and multi-channel imaging, and the experimental results are presented.
