Low-Cost High Bandwidth Fast Steering Mirror (FSM)

Fast steering mirrors (FSMs) have become a critical element to meet the demanding performance needs required by high energy laser weapons.  Stringent requirements for precision pointing, high power laser handling capability, optical surface figure, high bandwidth, and stressing operating conditions have driven advancements in FSM technology.  However, the high level of complexity required for these devices has resulted in extremely high-cost systems. All the while, commercial FSMs are available at significantly reduced costs, albeit with an inability to operate in the high vibration environments required for military systems.   During the Phase I program, Adsys Controls performed a preliminary design for a low-cost high performance FSM based on commercial technology.  During the Phase II program, the FSM and digital controller design will be completed and a prototype will be manufactured.  The device will be tested to validate the design and performance under objective environmental conditions.
