摘要
介绍了日本80年代的新产品光位敏器（PSD）及半导体激光器（LD），对PSD和LD的工作原理进行了分析，讨论了由PSD－LD组成的“光－位置传感器”测量硬度的可行性，并对由PSD－LD组成的“光－位置传感器”在其它领域的应用作了探讨。
This paper gives an introduction of the advanced product, PSD and semiconductor laser(LD ) produced by Japan in the 1980s, analyzes the working principle of PSD and LD, and discusses the possibility that 'laser-position sensor' consisting of PSD-LD makes measurement on the hardness. Also, it discusses the application fields of the unit.
