摘要：为满足对物体对象的非接触、高精度快速测量定位需要，在分析了目前位置检测技术的基础上，利用一维位置敏感元件（PSD）设计了一种物体位景检测系统，详细介绍了PSD位置检测的原理，通过单片机实现了对物体对象位置信号的采集处理，并把结果显示在上位机中；结果表明，整个检测系统响应速度较快、测试精度较高，可以达到士5％，实现了对物体对象的非接触精确测量定位。可应用于对精度要求较高的各种精密测试领域。，

Al~tmct： In order to meet the need of the non--contact and high--precision fast positioning about the object, based on the analysis of the current position detection technique, an object position detection system based on PSI） is designed, The principle of the PSD position de- tection is introduced in detail, It is achieved that the object position signal acquisition and processing through SCM, and the results are dis- played in the PC. The results showed that the detection system response speed is fast, the precision is high, and can reach ±5%, the experi- mental purposes is achieved , and this system can be used in high precision accuracy test field.
