Abstract

Method for equalization of temperature-induced non-uniformities in microbolometer IR FPA response based on use of variations of preliminary heating and measuring bias pulses applied both to sensitive and compensating bolometers is proposed. Carried out numerical simulation of proposed FPA architecture demonstrates high quality of signal equalization over wide temperature range that allows to apply microbolometer FPA indoors without use of any additional measures such as temperature stabilization and real-time correction.
