Research abstract
Imaging ladar systems for applications such as seekers on autonomously guided munitions must be compact, inexpensive and reliable. These systems often have a pointing system that consists of a fine-steering mirror (FSM), typically a small high-bandwidth two-axis optic and a course-steering mirror (CSM), typically a full-aperture large-travel optic or a gimballed telescope. This proposal seeks to reduce the mass, volume, power and complexity of the system by combining the FSM and CSM functions in one full-aperture high-bandwidth large-travel FSM. Full-aperture optics with ±175mrad mechanical travel exist, but their servo control bandwidth is limited by large-travel-specific factors. Increased bandwidth must be achieved without sacrificing pointing precision, surface figure, low mass, size or power performance. LHDC’s large-travel FSM currently achieve a -3dB closed-loop servo control bandwidth of >200 Hz. The bandwidth of these FSM is limited by bending modes that are coupled to the servo at full travel. This proposal is to increase servo bandwidth with an innovative suspension with an innovative, stiffer and lighter suspension.
