前言全息照相是60年代发展起来的一门体视摄影和波面再现的新技术。60年,世界上生产出第一台激光器后,激光在医学方面就得到广泛的应用。在临床上作为一种主要的治疗手段,并首先应用于眼科。由于激光是一种空间和时间的相干光源,利用光的干涉和衍射进行全息记录和再现。通过相干光的干涉能把物光波中振辐和位相的信息全部记录下来。波前再现时,能再现出被摄
Introduction Holographic photography was developed in the 60s as a new technique for stereographic photography and wavefront reproduction. After 60 years, the world’s first laser was produced and the laser has been widely used in medicine. Clinically as a major treatment, and first applied to ophthalmology. Since laser is a coherent light source in space and time, holographic recording and reproduction are performed using light interference and diffraction. Through the interference of coherent light, the information of vibration and phase in the light wave can be recorded completely. Wavefront reproduction, can reproduce the photo
