Micro Gimbal with Gradient Index Lens Technology

Building on our experience in fiber lens array beam steering, gradient index optical component design and fabrication, and high quality precise optical system design, AGILTRON proposes to produce an micro gimbal with gradient index lens technology. 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.
