The Characteristics of conventional photoelectric devices and selecting skills

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.
