Paper Abstract

Gimbals and Fast steering mirrors (FSMs) are commonly used to stabilize the line-of-sight (LOS) of the electro-optical tracking system mounted on moving platforms .The gimbal is used to restrain the vibration of low frequencies, and the FSM is used to restrain the vibration of high frequencies. The restraining performance of the Electro-Optical tracking system is equal to the multiplication of the restraining performance of the gimbal and the FSM. The vibration of high frequencies is mainly restrained by the FSM, and so the performance of the FSM is very important to the Electro-Optical tracking system. There are two ways to improve the stabilization accuracy and bandwidth of the FSM, one way is to improve the accuracy and bandwidth of inertial sensors, and the other way is to use low weight inertial sensors to reduce the load of FSM and increase the mechanical resonance frequency. And so the inertial sensors of high accuracy, high bandwidth and low weight are the key to improve the stabilization accuracy and bandwidth of the FSM.
