Abstract

SCD Focal Plane Arrays (FPAs) are based on 320×256 InSb elements, or 640×512 InSb elements. In this paper we introduce the outstanding FPA based on the signal processor 'blue fairy' (BF) that has been designed at SCD, and is now in standard production for the 320×256 InSb FPAs. The BF Focal Plane Processor (FPP) enables integration capacity of more than 15Me- at Integrate While Read (IWR) mode, and more than 30 Me- at Integrate Than Read (ITR) mode. A combined mode for large dynamic range with high sensitivity is possible. An excellent linearity and residual non-uniformity is achieved, starting from extremely low electron capacity up to 13Me- at IWR mode and 24Me- at ITR mode. Many other modes can be selected via a communication channel such as: ITR/IWR, one of seven different gains, one of seven different biases for the detector, windows size and window location. A Correlated Double Sampling (CDS) between frames and rows can be used for low frequency noise reduction, and/or any external electronic gain and offset drift corrections. All these features enable the integration of the BF FPA in large variety application, with high performance at each application.
