•Infrared Cold Camera Shutter

Client Need:

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.

Client Testimonial:

“Our cold shutter is working well in space and I have been out of town presenting the technology at several speaking engagements.  Thanks to 3-D for all your hard work and success in the development of this product. The Navy is very happy with the results.” Scientist, Government Development Lab
