1.序言 在红外遥控系统中,光电二极管(又名光敏二极管)与光电三极管(又名光敏三极管)都是红外接收管,它们把接收到的红外信号先变成电信号,再经放大及信号处理后,用于各种控制领域。除了用于红外遥控外,还可用于光纤通信、光纤传感器、工业测量、自动控制、火灾报警器、防盗报警器、光电读出装置(如纸带读出器、条形码读出器等)、家用电器控制及光电耦合器等方面。下面,介
1. Preface In the infrared remote control system, the photodiode (aka photodiode) and the phototransistor (aka phototransistor) are infrared receiver tubes. They turn the received infrared signal into an electrical signal first, and then amplified and the signal After processing, for a variety of control areas. In addition to infrared remote control, but also for optical fiber communication, optical fiber sensors, industrial measurement, automatic control, fire alarm, burglar alarm, photoelectric readout devices (such as tape readers, bar code readers, etc.) Electrical control and optocoupler and so on.
