光电编码器是光、机、电技术相结合的产品,被称为计算机与机械设备相联的桥梁。它通过光电转换,将机械设备轴的机械变化量、几何位移量等转换成相应的电脉冲信号或数字量,输送给计算机或显示仪表,计算机根据这些信息发出指令,实现自动控制。我国现有的三百多万台旧机床中,约有六十多万台需要改造。要使这些机床实现自动控制,必须使用光电编码器。另外国内每年生产的各种数控和自动化机床,也需要大量的光电 Optical encoder is a combination of optical, mechanical, electrical technology products, known as the computer and mechanical equipment associated bridge. It is through photoelectric conversion, the mechanical equipment shaft mechanical changes, the amount of geometric displacement into the corresponding electrical pulse signal or digital, sent to the computer or display instrument, the computer issued instructions based on these information, to achieve automatic control. Of the more than 3 million old machine tools in our country, about 600,000 need to be rebuilt. For these machines to be controlled automatically, optical encoders must be used. In addition, the annual domestic production of various CNC and automatic machine tools, also need a lot of optoelectronics
