InSb focal plane arrays with frame accumulation

Indium antimonide MWIR Focal Plane Array (FPA) have been developed and investigated. FPA consists of two dimensional arrays of InSb photodiodes bonded by indium bumps with CMOS-multiplexer and LN2 cryocooler. Noise equivalent power NEP≈1×10-12 W/pixel and dynamic range 60÷70 dB at frame frequency 250 Hz.
