ABSTRACT:
Automatic control method and system for EBCCD sensor. The invention relates to a novel protective method of operating the Electron Bombarded Charge Coupled Device (EBCCD), a recently developed, high sensitivity, low noise, and expensive focal plane array sensor. In particular, the invention provides a method for operation that automatically controls the EBCCD gain at a very high rate. This allows i) for sensor damage protection from too much light, ii) for extension of sensor service life by reducing gain in periods of non-use, and iii) for automatic gain adjustment to rapidly compensate for variations in scene brightness.
