Paper Abstract

The performance of fast steering mirrors is frequently limited by the presence of mechanical resonances. This paper studies the addition of damping material to the rotor or mirror of a galvanometer-based fast steering mirror in order to reduce the effects of these resonances. Both analytical and experimental efforts document the relative effectiveness of rotor versus mirror damping as a function of mirror size. The results indicate that the addition of damping material can result in a reduction in step response time.
