This is a continous work of 3744.

I replaced the mirror mount from LIOP-TEC's steering mirror to a rigid lens mount. Even with this new mount. there is still a peak structure around 600-700 Hz. This indicates that this resonance originates from piezo+mirror mainly, not from springs of the steering mirror
