ABSTRACT:
What is disclosed is a preamplier used with each pyroelectric detector in an infrared imaging array system. To construct each preamplifier and an associated detector in a dense detector array, solid state manufacturing techniques are utilized. To bias the preamplifier either a high bias impedance is effectively provided by doping the material from which the detector is made; or a MOSFET bias switch is provided that is periodically operated to place charge on the gate of the preamplifier transistor to maintain it at its bias level. When the bias switch is not operated, the associated detector detects and a reading is taken from each detector in the array.
