Enhanced-Bandwidth Fine-Steering Mirror, subtopics A, C, D and E

"This is an innovative approach to achieving a higher servo control bandwidth with fine-steering mirrors. Theprimary anticipated result of this SBIR is a control bandwidth of 4000 Hz for a fine-steering mirror for a 15 mmoptical beam and a 2800 Hz bandwidth for an FSM for a 35 mm beam. These are currently needed for SMDC'sinterceptor seeker applications. Achieving this bandwidth in the larger mirror will reduce the number of pointingmechanisms thus potentially reducing the size, mass, complexity and power consumption of the seeker system.These are high-performance fine-steering mirrors in terms of low mass, low surface figure errors and compactvolumes.Servo control bandwidth limits the ability of pointing and tracking systems to correct vibrations of the hostplatform which induce optical jitter causing blur.During Phase I, LHDC will conduct analysis and determine specific design features to enhance bandwidth. Designmodifications will be retrofitted to existing inventory units and characterized through test. Successful designfeatures will be incorporated into a Phase I conceptual model to be implemented in Phase II. The primary application is an FSM for 15 to 35 mm optical beams which are currently needed for SMDC'sinterceptor seeker applications.Other aerospace programs that can use the proposed technology include NRL's interceptor seeker programs, NextGeneration Space Telescope (NGST), Earth Observation System (EOS), Space Inter
