所谓的传感,一般就是把温度、长度、位移、压力、速度、电位、颜色等物理量变换成电量,表示成人五官理解的形式的技术。因此,可以利用各种物理媒体、物理效应。在物理效应中采用最多的是容易以电信号形式取出输出信号的电、磁效应。 近年来,融合进了光电子技术的光传感技术发展很快。光传感中的光有各种特 The so-called sensor, is generally the temperature, length, displacement, pressure, speed, potential, color and other physical quantities into electricity, that adult form of understanding of the form of technology. Therefore, various physical media and physical effects can be utilized. The most used in the physical effects is easy to take the form of electrical signals output electrical and magnetic effects. In recent years, optical sensing technology integrated into optoelectronic technology has developed rapidly. Light sensing light there are various special
