TEMPERATURE SELF-COMPENSATING TECHNOLOGY OF PHOTOELECTRIC DETECTING SYSTEM

The basic parameters of photoelectric components vary with ambient temperature. This seriously influences the temperature adaptability of the photoelectric detecting system composed by them. The principle of temperature selfcompensating technology used in the photoelectric detecting system is analyzed with the theory of signal and system. With this technology,the forward current of lightemitting component used in our photoelectric detecting system has been effectively adjusted. Therefore,temperature selfcompensating function of photoelectric detecting system has been achieved.
