条码识别系统中的光电信号处理

Opto-electronic Signal Processing in Barcode Recognizing System

摘要:

条形码技术是在计算算机应用实践中产生和发展起来的自动识别技术。本文介绍一种全息光盘条形码阅读器，它具有扫描速度高、景深大、扫描光照度强、扫描距离远、多方位万向扫描等特点，因而能广泛应用于对自动化程度要求比较高（如超级市场的ＰＯＳ系统）或者适合无人操作的（如集成电路芯片生产过程中的质量检验）场合。此外，它还可应用于铁路、公路交通运输管理中。本文主要介绍全息光盘条形码阅读器的光学系统结构；光电探测的设

Abstract:

Barcode technology is one auto-recognizing technology which was generated and developed in computer applying. This paper will introduce Hologram Disk Barcode Scanner,which has many advantages, such as high scanning speed, large power scanning light, far-distance scanning and omnidirection scanning So it is used in many areas such as POS system. This paper is mainiy introduce it's optical system,opto-electronical detective and opto-electronic signal processing.
