It includes four key optical modules: (1) precise pointing module; (2) coarse pointing module; (3) angle magnifier module; and (4) laser designator module. The precise pointing module is able to point the light beam to any direction within a small field of view (SFOV) with high accuracy and up to 1kHz rejection bandwidth. The coarse pointing module is made of micro gradient index lens arrays. It controls the SFOV��s central direction within a big field of view (FOV) of up to 26,a cone angle. The angle magnifier module further increases the working FOV to 130,a cone angle. With this micro gimbal, Agiltron in cooperation with Fibertek will develop a miniature laser designator system that meets all the requirements of this application. In the Phase I program, a detailed analysis of the configuration, key part design and feedback loop models will be carried out, supporting experiments and a functional demonstration prototype will be conducted. Benefits: This effort will greatly reduce gimbal optics size, weight, cost, improve the bandwidth, pointing accuracy, agility, reliability, efficiency, stability and performance, and will extend the spatial resolution. The integrated mini laser designator will find direct use in NAVY laser illuminator systems. By matching a suitable gradient index material, the technology is also effective for other applications, such as LADAR, free-space communication. Return
