【Abstract】 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.更多还原
