Abstract
|
Diffraction optics is an emerging discipline in the field of modern optics. Diffraction optical element can realize arbitrary phase modulation of light waves have very unique dispersion properties; These features make the diffraction optics in the optical system has a good application prospect. Diffraction optical element is the most important parameter is the diffraction efficiency, before application of the underlying factors restricting the diffraction optical element is processed by the diffraction device of the diffraction efficiency is too low; The problem of low efficiency of diffraction with diffraction optical design theory and the progress of modern processing technology and gradually resolved. This article first chapter the introduction Outlines the diffraction optical development course, and derived the this topic research direction and research significance; The second chapter introduces the theory of diffraction optical base, including working principle and imaging characteristics of diffraction optical element; In the third chapter, we introduced the diffraction optical element is combined with traditional optical system composed of folding diffraction general design principle and the advantages of the hybrid optical system, and designed a set of diffraction hybrid folding telescopic lens system and a set of flat like a fold diffraction hybrid eyepiece system; The fourth chapter discusses the diffraction optical element diffraction efficiency test plan, and measure the actual design process can be used as a telescopic lens by folding the diffraction hybrid single lens diffraction efficiency;
