Abstract
The invention provides a flexible anti-rotation mechanism for a two-dimensional rapid reflector, especially relating to a device used for restricting the revolution of the two-dimensional rapid reflector around a central shaft, wherein a restriction center is a ball-type hinge. The mechanism comprises a mirror seat, four straight voice coil motors, a pedestal, a flexible spring and the ball-type hinge. The pedestal is connected with the pedestal through the ball-type hinge. Each of the straight voice coil motors is composed of a coil and a magnetic support. The coil is fixed on the pedestal to form an immovable part. The magnetic support is fixed on the mirror seat to form a movable part with the mirror seat. The flexible spring is fixed between the pedestal and the mirror seat, through elasticity of the spring, that the movable part deviates along an X axis and a Y axis for less than or equal to +/-30' can be realized, and degree of freedom of rotation of the movably part along a Z axis is restricted through inherent rigidity. Repeat accuracy of rapid reflector high frequency reciprocating motion is ensured fundamentally, and work reliability and stability in a power off state of a system are raised greatly.
