一、全息摄影的基本原理照相摄影技术,从发明到现在一百多年来,都是根据几何光学的原理,利用透镜光学系统,使立体的景物成象于感光材料上,然后在照相纸上显现出景物的平面象。各种型式的立体摄影也不越出这一范围,只是在一张(或两张)照相纸上摄录立体景物某几个方向的平面象,通过柱面透镜板或体视镜等进行观察,利用双眼体视效应,从而看到具有立体感的景物影象。近十多年来,由于激光的出现,才使照相摄影
First, the basic principle of holography Photographic photography, from the invention to the present one hundred years ago, are based on the principle of geometric optics, the use of optical lens system, so that the three-dimensional image of the scene in the photographic material, and then in the photographic paper Showing the landscape of the plane icon. Various types of stereoscopic photography do not go beyond this range, just one (or two) of the photographic paper on the three-dimensional scene of a certain direction of the plane image, through the cylindrical lens or the endoscope to observe , The use of binocular stereoscopic effect, so as to see the three-dimensional image of the scene. In the past ten years, due to the appearance of the laser, photography was taken
