Paper Abstract

This paper presents a novel method to fabricate circular gratings based on binary optics. A smart digital micro-mirror device (DMD) laser writing system is used to fabricate circular gratings. By use of the DMD system, we are capable of making low-cost and useful circular gratings easily. Their levels and radii can be controlled and be suited for many optical systems. Experiment results have been obtained with two and four levels. In this paper, it will also show a method of simulating circular gratings' diffraction. Using the simulation method, we can value and check the diffraction effect of circular gratings to rectify the design parameters.
