Abstract

I nfrar ed imagery is quite a field of interest for military as well as for biomedical research today. Our target is to develop an integrated readout circuitry for single pixel infrared sensor . We have put our efforts into developing an Infrared imagery system, wh ich is cost effective, batch producible. We have developed the readout circuitry for the system i.e. signal conditioning unit, data processing unit, and display. The system so developed will work as a single pixel of an IR camera or “IR thermometer” . The c ircuit is designed to match specifications of IR thermometer for human body. The requirements of system are studied and implemented on simulations. The prototype of the circuit is prepared and tested. We have also tested suitable materials for the IR senso r. Materials such as graphene doped Mn 2 O 3 and GeO 2 are tested as candidates for IR sensors. Interesting results about materials are obtained, however they need to explored deeper.
