This article introduces the working principle of optical glass ECT and analyzes the accuracy of optical glass ECT,which indicates that the DC bias of the photodetector will lead to contrast overrun.A brief description is given of the photodiode principle and current-voltage conversion circuit,and a further discussion is made of the causes of the photodetector DC bias and its solutions.The test proves that our light detector meet the system accuracy requirements of optical glass ECT.

Key words: optical glass ECT;photodetector;DC bias
