全息法改善大口径菲涅耳透镜的成象质量

IMPROVEMENT OF IMAGE QUALITY OF THE LARGE APERTURE FRESNEL OPTICAL LENS BY HOLOGRAPHY

提出一种根据象面全息法改善有机破璃制大口径菲涅耳透镜成象质量的方法。给出了“全息干版”和“光导热塑片”制备的两种“补偿板”对菲涅耳透镜进行象质改善的实验结果。

This paper describes the method of improving image quality of a largeaperture Fresnel plexiglass lens by means of image plane holography. The experimental results are given of the two kinds of compensation plates consiting of hologram plate and photoconductive thermoplastic plate for improving image quality of the Fresnel optical lens.
