一、前言全息光学透镜具有常规光学元件所没有的优点,它体小、质轻、形状可变。但是由于制作它的全息记录材料衍射率低(银板30％,铬板80％),所以,其成象质量在一般应用中不如常规光学透镜清晰。我们曾多次将其作为物镜,在同一波长和白光下对物体照相,其分辨率都比常规光学透镜成象差。所以,我们将其置于4f光学系统中进行信息处理。 I. Introduction Holographic optical lenses have the advantages of conventional optical components, it is small, lightweight, variable shape. However, since the holographic recording material from which it is made has a low diffraction rate (silver plate 30%, chrome plate 80%), its image quality is not as good as conventional optical lenses in general use. We have repeatedly used it as an objective lens to photograph objects at the same wavelength and white light, all at a lower resolution than conventional optical lens imaging. So, we put it in the 4f optical system for information processing.
