Abstract :
This paper describes the transient response of an automatic gain control (AGC) with multiple thresholds for intensity in an image-intensified camera. Similar examples have flown in intensified-video systems used in satellites. The paper develops a stable AGC with an improved transient response over the system described in previous work. The improved transient response uses the integrated scene brightness at various intensity thresholds.
