The Characteristics of conventional photoelectric devices and selecting skills

在光电技术产业化过程中,光电器件的重要性日益显现。光电器件的种类很多,功能各异。如何掌握各种光电器件的特性及正确选用光电器件是光电技术实际应用中的关键。在对一个光电系统的性能指标进行评价时,系统所选用的光电器件的性能参数指标已经成为最重要的影响因素之一。本文介绍了常用光电器件的主要特性,对常用光电器件进行了对比。讨论了光电器件应用选择时的注意事项与技巧,并对选用光电器件的基本原则进行了总结。

During the process of photoelectric industrialization, the importance of the photoe- lectric devices and appliances shows increasingly. There are many categories of photoelectric devices and applications, their functions are different. How to grasp their characteristic parameters and choose the right forms is the key of practical applications＂ technique. While carrying on an evaluation to the functions of a photo electric system, the parameters of the chosen devices and appliances have already become one of the most important influencing factors. This text introduces the characteristic parameters of conventional photoelectric devices and gives contrasts to the different devices and appliances. It also discusses the choosing reg- ulations and skills to the various applications, selecting principles. and carries on an overall summary to the basic selecting principles.
