Current Multiple Integrated Laser Engagement System (MILES) transponders cannot penetrate the low-visibility conditions that thermal infrared target acquisition Systems can see through. However, recent breakthroughs in nonlinear optics make it possible to develop new, low cost, high energy efficiency, solid-state laser sources that can provide MILES operational capability up to the limits of conventional thermal imaging. Coherent Technologies, Inc. (CTI) has applied these technologies in the Phase I program to develop an innovative 4 micron wavelength MILES transponder design that will operate in foul weather, dust storms, and oil smokes. The design is being fabricated and tested to ensure low technical risk for Phase II. The mid-wave infrared transmitter-receiver pair provides backwards compatibility with existing MILES codes and eyesafe operation in a rugged, compact package. The configuration utilizes commercially available components and leverages CTI's experience in IR lasers and turnkey laser systems for severe environments to provide a low risk approach to achieving the next-generation MILES performance goals. In Phase II, CTI will delivery new MILES prototypes. Benefits of the new technology to the Army include improved troop training effectiveness and reduced training costs. BENEFITS: Eyesafe engagement simulators, intermediate-range line-of-sight optical communicators, search and rescue beacons, identify friend or foe, short-range vehicle collision avoidance sensors, active illuminators for mid-wave cameras, intermediate range pollution lidar sensors, motion and obstruction detectors.
