SBIR-STTR Award

A design for a long-wave IR integrated dewar assembly that includes a lens in place of a window, and the associated, deterministic alignment processes, fixtures and instrumentation will be developed. Including a lens, instead of a window, in a dewar provides additional optical design freedom that makes it possible to reduce the length and weight of a sensor optical system. Size and weight are critical performance of sensor optical systems for kill vehicles. The assembly processes will take advantage of the point source microscope, whose principles have been demonstrated and documented. Deterministic assembly processes are necessary to control costs as well as for mission assurance.

A versatile and portable instrument for stray light detection and diagnosis at both visible and infrared wavelengths will be designed, built, and demonstrated. The core idea of the proposed approach is to use subaperture, rather than full aperture, illumination for stray light detection. The subaperture approach uses a scanning pencil beam (SPB) that provides information about the location of a stray light defect, accelerating diagnosis of the stray light defect. The use of subaperture illumination in the SPB results in a smaller test instrument making a portable instrument possible.
