Abstract
Several APD photon-counting systems have been studied for linearity of response as a function of light intensity using a controlled LED light source. The effectiveness of the APD as a photon detector at high rates is limited by various types of non-linear response above 100 kcounts/sec. Two types of APD non-linearity, and the way each distorts a reference pulse, will be discussed. “Undercharged” APDs can cause distortion at quite low counts rates, and dead-time effects can cause distortion at count rates which approach the inverse recharge time.
