摘要
通过物体上光的变化,我们很难了解到其中包含的信息,而光电式传感器可以作为一种转换装置将其经过一系列处理形成电信号以便于人们理解的形式展现出来。光电式传感器最基本的部件组成为光电元件,基于不同种类的光电效应得到了不同类型的光电元件,例如光敏电阻。于此同时,这些光电元件的基本特性存在较大的差别,通过它们的特性可以对其适合的应用领域进行分析,以发挥其最大效益。光电式传感器的应用场合较为丰富,这归因于其较高的测量精度以及非接触的特性。
It is difficult to know what information is contained in the change of light in an object,but the photoelectric sensor can be used as a conversion device to present it in the form of an electrical signal that can be processed in a series of ways for people to understand.The most basic components of the photoelectric sensor are composed of photoelectric elements.Different types of photoelectric elements,such as photosensitive resistors,are obtained based on different types of photoelectric effects.At the same time,the basic characteristics of these photoelectric components are quite different,through their characteristics can be suitable for the analysis of the application field,in order to give full play to their benefits.The applications of photoelectric sensors are abundant,which is due to their high measurement accuracy and non-contact characteristics.
