1.引言全息照相术是记录物光波面与参考光的干涉条纹,再由记录了干涉条纹的全息照片的衍射光再现原来物光波面的技术。因此,对于全息照相记录用的感光材料的要求首先是对所记录的光波长量级的干涉条纹具有尽可能高的分辨本领(大约2000条/毫米)。其 I. INTRODUCTION Holography is a technique of recording the interference fringes of light waves and reference light and then reproducing the light waves from the diffracted light of a hologram recorded with interference fringes. Therefore, the requirements for photosensitive materials for holographic recording are first of all to have the highest possible resolving power (approximately 2000 bars / millimeter) for the recorded interference fringes of the order of light wavelengths. its
