拍摄脉冲全息肖象母版的研究

STUDY ON MAKING PULSE PORTRAITS MASTERS

本文介绍了我们在拍摄脉冲全息肖象母版方面的研究工作．讨论了拍摄工作中所需要特别注意的若干问题．如：人眼安全、对易律失效、消除双频条纹、如何获得高亮度图象等问题．此外，还介绍了我们拍摄脉冲全息母版时，在未使用Q开关的情况下，同样获得了高质量全息肖象母版的经验．

This paper describes the works which have been done in our lab on making ruby laser pulse masters (H1). It deals with some problems of interest such as safety illumination of human eye--sight ;high intensity reciprocity failure (HIRF);the relationship between the coherence length of the laser and depth of hologram;the method of eliminating the contour fringes at a single exposure hologram and the experience of making pulse master by using a ruby laser without the Pockels cell.
