摘要
本文着重介绍了透射式和反射式光电传感器的基本原理。并以反射式光电传感器为例，说明如何根据不同的色差选择光源色。最后介绍了光电传感器在包装机械和计量装置上的几种典型应用。
This article emphatically introduce the basic principle of transmissive photoelectric sensor and reflecting photoelectric sensor and illustrate how to chose the colour of light source according to different chromatism by the example of reflecting photoelectric sensor. In the end it introduce several typical application of photoelectric sensor to packaging machine and measuring device.
