In Phase I, optical modeling and measurements supported the technical feasiblity of a first-of-its-kind open architecture, multiple aperture, active electro-optics sensor. The hardware design generated and proposed for Phase II can achieve port selection, target fine-tracking and adaptive field-of-view-functions without moving parts via innovative liquid crystal devices. The principal objective of Phase II is a systems level demonstration of the multiple functions of rangefinding, imaging and designation out of multiple ports with robust direct detection receivers. Importantly, the base design is compatible with future upgrades to coherent detection laser radar functions, and with module-level line replacements that take advantage of technology advances. Additionally, the work will complement current Air Force programs that integrate passive and active sensors. When this innovative system architecture is coupled to CTI's experience in developing turn-key flight-qualified EO systems, new, lower cost and higher performance air combat sensors can be built. Applications include high resolution range-finding, atmospheric aerosol pollution monitoring, aerial topography and non-cooperative target imaging and surveillance.
