ABSTRACT:
The present invention provides an x-ray sensor that converts x-ray radiation into infrared radiation using a high mass number material. The infrared radiation that results from this conversion is then detected using a superconducting detector. The superconducting detector uses a superconducting material for each of a plurality of detector elements that are temperature biased at the superconducting-nonsuperconducting transition temperature. As infrared photons strike one of the detector elements, the temperature of the superconducting detector element increases, which causes an increase in the resistance of the detector element. Using the output of each detector element an image of the original x-ray radiation is obtained.
