纵扫描法计算全息扫描器的研制

Study on Longitudinal Scanning Method Used for Fabricating CGH Scanner

介绍了纵扫描的计算全息扫描器的基本原理 ,并对此种扫描器如何调整扫描图形的位置、大小 ,以及优化扫描结果提出了一系列方法。给出了计算机模拟实验和相应的光学实验结果。对此种扫描器实现彩色曲线扫描以及同时实现多点扫描进行了一些探索 。

The theory of longitudinal scanning in computer-generated hologram (CGH) scanner is introduced. A series of methods of how to change the position, size of the scanning curve and how to improve the quality of image are described. The computer simulating result and experimental result are presented. The paper also discusses how to scan color curve with CGH scanner and the computer-simulated result is presented.
