ABSTRACT:
A highly sensitive non-refrigerated sensor configured in a microwave bridge to receive incident radiation from a remote target or source. A test arm of the microwave bridge has an aperture for receiving the incident radiation and for allowing that radiation to enter the test arm. A photoconductive film is mounted within the test arm to receive a defocused image of the target. The effect of the incident radiation illuminating the photoconductive film is to change its conductivity characteristics and simultaneously change the reflectance/transmittance characteristics within the test arm of the microwave bridge. An RF detector senses the imbalance of the bridge and produces an output which is used to either indicate the strength of the received incident radiation or to feedback information to a reference arm of the bridge. The feedback information is used to adjust the phase and amplitude of the microwave energy in the reference arm and rebalance the bridge.
