Abstract
A thermal radiation sensor is disclosed wherein a semiconductor thermocouple comprised of a pair of silicon diodes is connected in back-to-back relationship, with one of the diodes being located in a detector stage. The other diode is located in a heat bath stage together with a sensed temperature difference amplifier. The detector stage is thermally isolated from the heat bath stage by a low thermal conductivity link that includes electrical wires which connect the back-to-back diodes to the amplifier.
