Patent ID: 8440972

Claim:
A radiation detector comprising: a frame; plural pixels that absorb photons from incident radiation and provide a mechanical response to heating by absorption of the photons; and means for measuring the mechanical response of the pixels to the heating by absorption of the photons; wherein the pixels are within the frame and the pixels each include a pad for absorbing the incident radiation, wherein the pad comprises a first layer of black (microstructured) silicon, a second layer of mercury cadmium telluride, and a third layer of silicon nitride; and a pair of arms that attach the pad to the frame; wherein each arm includes at least one bimaterial portion adjacent to at least one isolated portion such that the bimaterial portion comprises a stacked layer of different materials with different thermal coefficients that deflect upon heating due to different coefficients of thermal expansion of the materials of the bimaterial portion, and the adjacent isolated portion comprises a single material or multiple materials with similar thermal coefficients.
