Abstract

This paper describes the circuit techniques used to implement a flexible set of correction, control and drive modules for use with a range of photovoltaic, Infrared arrays. The system consists of a set of modules inter-connected via both data and parameter busses. This structure allows selection of the appropriate set of modules for any desired IR array, whilst maintaining the same data and control formats. This approach allows several units to be connected in parallel to process many pixels, either from many conventional (-104 detectors) arrays or from a single larger array. We examine the problems of interfacing both high speed clock waveforms and low level signals to the dewar. The correction processes are described together with the importance of a common output format suitable for a wide range of users. The format has been selected to allow the future use of new generations of monolithic digital signal processors. The flexibility of this electronics allows it to be extended to form a programmable assessment system capable of measuring Infrared arrays under realistic operating conditions. Finally we present results obtained from this system in conjunction with a variety of arrays.
