A system for sensor thermal management and stabilization comprises a sensor block, one or more sensors mounted on the sensor block, one or more heaters mounted on the sensor block, a chassis coupled to the sensor block, a thermal conductor moveably coupled between the sensor block and the chassis, and a thermal control actuation mechanism operatively connected to the thermal conductor. The thermal control actuation mechanism is operative to cause the thermal conductor to vary a total thermal conductance from the sensor block to the chassis by moving the thermal conductor toward the chassis or away from the chassis. The total thermal conductance is varied to provide an optimized thermal stability and optimized environmental range of applicability for the one or more sensors.

Embodiments described herein relate a tunable heat transfer system. The tunable heat transfer system includes a controller, a first body, and a second body. The first body is communicatively coupled to the controller. The second body is communicatively coupled to the controller and spaced apart from the first body. The second body has a plurality of semimetal layers and a dielectric portion positioned between each of the plurality of semimetal layers. Each of the dielectric portions has a thickness to define a gap between each the plurality of semimetal layers in an expanded state and permitting each of the plurality of semimetal layers to abut each other in a contracted state. The controller is configured to change a near-field radiative heat transfer between the first body and the second body by changing the thickness of each of the dielectric portions between the expanded state and the contracted state.
