Infrared Cold Camera Shutter

 

 

Client needed a "Cold Camera Shutter" system developed to provide a means to make true "In-Situ" radiometric measurements to provide the ability to detect plume exhaust. The project utilized an IR imaging camera containing precision optics and sensors packaged within a cryogenically cooled (LN2) vessel.

3-D Engineering Solution:

3-D Engineering Corporation performed a thorough review of existing packaging design and identified all relevant specifications and requirements, specifically: size constraints, thermal requirements (temperature extremes and thermal insulation requirements) and shutter interface/interaction requirements and conducted a study of all off-the-shelf shutters and shutter mechanisms in general, examining electrical and mechanical methods of shutter actuation including contact and non-contact design approaches. 

Results:

3-D Engineering successfully integrated a reliable cryogenically cooled “Cold Shutter” into the assembly that facilitated zero radiance calibration and thereby optimized the performance of the camera system and recorded test data from performing the initial prototype testing.
