To detect small signal with bright background light,the photosensor must be high responsive for incident light and noise level is low. Avalanche Photo diode (APD) is good for detectingthe small signal at high brightness, because it has high efficiency by avalanche multiplication. In the cace of detecting very small signal, that level is usually 10^<-3>〜10^<-4> of background light, S/N ratio that depends on noise, is very serious problem. The purpose of this study is to measure the sensability limit of using APD at high level background light. As a result,it is come out that the sensability limit of APD is about 10^<-4> of background revel.
