Abstract
A fast steering mirror has n plate springs (to) and m drive means (to). The plate springs (to) are arranged such that a cross-sectional plane passing through the center of the thickness of each of the plate springs is on the same plane as the reflection surface of a mirror (), and are arranged rotationally symmetric to each other about the center (O). The plate springs each have a section extending along the circumference of the mirror holder, the section being obtained by dividing the perimeter of the mirror holder substantially into n sections. The drive means (to) are arranged such that a cross-sectional plane passing through the center of torque generated by each of the drive means is on the same plane as the reflection surface of the mirror () and are rotationally symmetric to each other about the center (O).
