    摘要: An assembly that enables precise mounting of a sensor with improved heat transfer and rotation compensation includes an integrated dewar cooler assembly incorporating the sensor. The dewar assembly is mated to a motorized mount that is controlled to stabilize the rotation of the scene. The sensor is radially aligned relative to the axis of rotation in two adjustment stages. A first stage of adjustment controls the radial position of the sensor inside a bearing. And a second stage of adjustment controls radial translation of the entire assembly outside the bearing. Passive heat transfer is accomplished through a pair of heat sinks that effectively sandwich a hot expander end cap of the dewar, providing multiple heat paths. The entire dewar assembly is rotated during operation to stabilize the scene. The rotating mass of a cooling compressor coupled to the dewar is counter-balanced to avoid torque due to inertia.

    摘要: A fluid cooled thermal management technique for a high-density composite focal plane array (CPFA) is disclosed. In one embodiment, a high density CFPA assembly includes a plurality of imaging dies mounted on a front surface of a printed wiring board (PWB) and a base plate. The base plate has a substantially matched coefficient of thermal expansion (CTE) to that of the high density CFPA. Further, the high density CFPA is disposed on a front side of the base plate. Furthermore, the base plate has a plurality of integral serpentine fluid flow channels configured to receive and circulate fluid and further configured such that the heat generated by the CFPA is transferred via conduction into the base plate and to the integral serpentine fluid flow channels and to the circulating fluid to dissipate the generated heat.
