ABSTRACT:
A bolometer for the detection of radiation includes a thin film of bismuth having electrical contacts formed at its outer boundary edge whereby electrical signals, as a function of the X and Y positions of input radiation, appear as output signals at the contacts. A measure of the radiant energy striking the detector is used to ratio X and Y to make the instrument insensitive to changes in power input.
