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.
A review of automatic gain control theory
The paper presents the general theory of automatic gain control (a.g.c). It includes discussions on loop gain, regulation and the relation between loop parameters and output level stability. An equivalent circuit is derived which is used in the study of dynamic behaviour. The work is extended to cover sampled data a.g.c. systems and design guidelines are derived for a variety of situations.
