A proposed method of infra-red detection based on thermal conversion of radiation

Abstract

A new method of i.r. detection is proposed, based on the change in Planck radiation of a black strip when it is heated by the radiation to be measured. The application of a photo-conductive cell is proposed for the detection of the Planck radiation which occurs in the near i.r. region at room-temperature. Some informative calculations on the detection limit will be given, showing that the expected results are good when compared with that of bolometers etc.
