摘 要
光电报警器的主要部分是光电传感器。传感器是指能感受规定的被测量并按一定规律转换成可用输出信号的器件或装置。通常由敏感元件和转换元件组成。传感器的原理有各种各样，其中光电式传感器，是将光通量转化为电量的一种传感器，光电式传感器的基础是光电转换元件的光电效应。由于光电测量方法灵活多样，可测参数众多，一般情况下具有非接触、高精度、高变率、高可靠性和反应快等特点，加之激光光源、光栅、光学码盘、CCD器件、光导纤维等的相继出现和成功应用，使得光电传感器的内容及其丰富，在检测和控制领域中得到广泛的应用。 关键词：光电传感器；光通量；光电效应；

Abstract
The main part of the photoelectric alarm is photoelectric sensor. The sensor is to point to the provisions of the measurement can feel by and by a certain rule can convert the output signal devices or device. Usually by sensitive components and convert components. The principle of the sensor there are all kinds of photoelectric sensor, and is transformed into electricity will flux sensor, a photoelectric sensor is the foundation of the photoelectric conversion of components of the photoelectric effect. Because the photoelectric measuring method agile diversity, can be measured parameters, usually have a contact, high precision, high change rate, high reliability and quick response characteristics, and laser light source, grating, optical code dish, CCD, optical fiber, etc have appeared and successful application, make the content of the photoelectric sensor and its rich, in the detection and control areas widely applied.
Keywords: photoelectric sensors; Flux; Photoelectric effect;
