Naval Ordnance and Electronics Research

Two programs of electronics research at the Naval Ordnance Laboratory are reviewed. These are photoconductor research and polarity coincidence correlation. In Part I an account is given of investigations of the lead salts, PbS, PbSe, and PbTe, which have led to a consistent theory of photoconductivity and infrared photoconductive detectors. In Part II the theory of polarity coincidence correlation is reviewed, and some of the considerations involved in developing equipment for particular applications are discussed.
