Abstract

The design of the Diffractive/Refractive optical system needs to strictly control the ghost image. It is proposed to divide the ghost caused by the strong light source and the field of view. For the ghost image caused by strong light sources in the field of view, in order to reduce the computational amount, the optical surface that can produce serious ghost is selected by Code V, the optical system is modeled in ASAP and gives appropriate refraction and diffraction properties to the optical working surface, and the light source with different incident angles is set to light trace to obtain the location and energy information of the ghost image. For ghosts caused by a strong light source outside the field of view, the scanning light source is directly set up for light tracing, and the transmission path of the ghost image is extracted according to the ghost location and intensity information of the focal surface to provide reference for the subsequent ghost suppression.
