全息扫描光盘设计研究

Research on the Design of Holographic Scanning Disk

本文介绍的激光多方位条码扫描器采用了全息光盘作为平面光学元件来实现激光束的扫描偏转和聚焦,设计了多面反射镜光学系统以形成多方位的空间扫描网.为实现弱光信号探测和对条码的高速实时识别,还专门设计了模拟信号处理及数字译码电路.给出了全息光盘的有关设计参数及实验结果.

The laser Omni-directional bar code scanner introduced here mainly consists of a holographic disk which as a plane optical element is to realize the laser beam deflection and focusing , as well as a series of mirrors designed for a scanning space. For high speed real time detection and recognition of weak light signals, the analog circuits and digital circuits are also designed, the design parameters related to the holographic disk and some experimental results are shown.
