摘要：
A piezo driven tilt mirror was developed and built as one component of an image motion compensation system for a solar telescope. The bandwidth of the mirror with a diameter of 60 mm is about 1 kHz with negligible phase shift between input signal and mirror response up to 900 Hz. The tilt range is 1.6 mrad. Special care was taken to maintain the surface quality of the mirror to better than lambda/15 after fixing it to the substrate.
