Infrared focal plane array processor with integrator and low pass filter per pixel

摘要

A circuit and method of detecting infrared radiations with a focal plane array circuit member comprising storing a charge in a storage device (13) indicative of the intensity of received infrared radiations, periodically transferring the stored charge (17, 19) and then resetting (15) the storage device, storing the transferred charge (21), providing an output terminal (29) and providing a low pass filter (25, 27) coupled between the output terminal and the storage means.
