1/24/2024 0 Comments Irad 900 mirror mount![]() There are many solutions available commercially for fast steering mirrors. The FSM was designed for ground test only. This paper covers the design, analysis, fabrication, assembly, and testing of this device. ![]() All solutions were thoroughly modeled and analyzed. The manual adjusters have very good resolution, with the capability to be locked in place. Special care was taken to insure the best positioning means with the mounted mirror assembly held kinematically in place. The adopted solution achieves a good mass balance and gimbaled motion about the center of the mirror front surface. The off-the-shelf Piezo translators (PZT) actuators enable reliable and repeatable closed loop control. The simple, yet very compact and rugged device also has manual tip/tilt/piston alignment capability. ![]() The design requirements were to gimbal a 5 cm diameter mirror about its reflective surface, and provide 1 KHz tip/tilt/piston control while maintaining λ/900 flatness of the mirror.
