Title: 15 歠cut-off 128x128 Quantum Well Infrared Photodetectors (QWIPS) Camera
Authors: Gunapala, S. D.

Abstract: We discuss the development and the performance of a very long wavelength (13.5 - 15 歩 128x128 AlGaAs/GaAs multiquantum well infrared imaging system. Highly uniform, high-yield QWIP focal plane array was hybridized to a CMOS multiplexer operating in a direct injection mode. For efficient light coupling an integral random scattering reflector (Random Grating) was incorporated. Due to the high uniformity, excellent imagery, low noise as well as a noise equivalent temperature difference (NE T) of less than 30 mK were obtained when operating around 45 K. Therefore, high image contrast signal to noise ratio has been achieved.
