AbstractABSTRACT: To address the Air Force need for a reduced-path-length solar/lunar exclusion sensor test capability that quantitatively characterizes off-axis rejection (OAR) of bright light sources for validation and calibration of sensors in a cryo-vacuum environment, Physical Optics Corporation (POC) proposes to develop a new solar/lunar exclusion projection (SLEP) system based on a novel integration of athermalized compact projection and polarization control optics and broadband light sources. The proposed SLEP design will deliver collimated source irradiance with known polarization characteristics over broadband infrared (1 to 20 micrometers) with a uniform intensity profile in a compact form operable in a cryo-vacuum environment. SLEP will measure sensor performance to nominally 1E-09/sr with a dynamic range of 14 orders of magnitude from 0 to 12 degrees with 0.1-degree angular resolution, which directly addresses the Air Force"s requirements for an OAR sensor test capability. In Phase I, POC will demonstrate SLEP feasibility by developing a concept design and proof-of-concept prototype that can operate in cryo-vacuum (80 K and 1E-6 Torr) conditions. In Phase II, POC plans to develop and demonstrate a fully functional engineering prototype that meets Air Force requirements for OAR sensor testing applications for space simulation chambers (30 K and 1E-6 Torr). BENEFIT: The proposed SLEP capability will address the need for a reduced-path-length solar/lunar exclusion sensor test capability that quantitatively characterizes off-axis rejection (OAR) of bright light sources for validation and calibration of sensors in a cryo-vacuum environment; therefore, it will meet Air Force space platform and test requirements (unlike current technologies) without requiring significant modification to existing hardware. The innovative system design allows reduced size, weight, and power (SWAP) and facilitates incorporation into an existing space simulation test facility. As a result, the SLEP technology will have cost and performance advantages over any competitors. These advantages include high resolution, wide spectral bands, and high dynamic range. Commercial applications of SLEP will include delivery and testing of advanced space systems. It will be applicable to on-board spacecraft systems and commercial space simulation test facilities. It can be used in many test facilities that operate at cryogenic temperature and need ground testing capabilities to characterize OAR sensors, such as in satellite industries.
