Abstract

Diffractive Optical Element (DOE) is a device forming a specific diffraction image on the image plane. Generally, it is calculated by iterative Fourier Transform Algorithm (IFTA) in the inverse direction from the three-dimensional information of the target image and incident beam. However, there is a problem that DC noise occurs due to various factors in conventional design method of DOE, and a lot of researches have focused on them [1, 2]. In this paper, we analyze the cause of DC noise from DOE and propose the noise reducing method when the designing the DOE. Moreover, we can recognize the conjugation noise in the binary DOE can be reduced using this method.
