A novel high sensitivity superconductive bolometer is presented in which the detector is kept in its superconducting state during the functional phase. Operation is based on detecting an induced fluxoid motion following a temperature rise caused by impinging infrared radiation. The superconductive-flux-motion-induced bolometer consists of a superconductive film and a pick-up film which are electrically insulated from each other. As the temperature of the current carrying film rises, fluxoid motion is triggered, sweeping through both films so that a voltage is detected in the pick-up film. The superconductive-flux-motion-induced bolometer has higher sensitivity for detection of infra-red radiation than any bolometer known heretofore.
