Research of Novel Circular Grating
Given that most of the optical systems are circularly symmetric, the Circular Dammann grating has wide application. However, its parameters’ design is a hard problem which restricts its development. This paper presents a new method to optimize the design of Circular Dammann grating with introducing quantum genetic algorithm and some appropriate revises. Compared with other design methods, it has obvious advantages. At the end of this paper, the simulation results are given.
