将硅光电负阻器件与发光二极管封装在一起,利用硅光电负阻器件的双稳和自锁特性,制成了一种新型的非线性阈值可调光传感器。研究表明,该光传感器不仅可实现对信号的光电耦合,还可实现设定阈值,比较判断和输出驱动等一系列信号处理功能;同时它结构简单,调整方便。 The silicon negative photodiode device and LED package together, the use of silicon photodiode negative bi-stable device and self-locking characteristics, made a new type of nonlinear threshold adjustable optical sensor. The research shows that the optical sensor not only can realize the photoelectric coupling of the signal, but also can realize a series of signal processing functions, such as setting threshold, comparing and judging and outputting driving, etc .; meanwhile, it has the advantages of simple structure and convenient adjustment.
