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.
