Transient response for automatic gain control with multiple intensity thresholds for image-intensified camera

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. This paper completes the development of a stable AGC with an improved transient response over the system described in a previous work. The improved transient response uses the integrated scene brightness at various intensity thresholds.
