Problems solved by technology
However, it still has the following problems: (1) The rotation angle of the mirror body cannot be detected in real time as the feedback for controlling the micro-displacement of the piezoelectric ceramic actuator. When the mirror mirror deflects due to vibration and impact, it cannot Under control, mirrors have poor vibration and shock resistance
(2) The overall height of the reflector is high, and the range of the deflection angle of the reflector is small

The invention discloses a one-dimensional fast control reflector, which includes a reflector, an outer frame and an actuator mechanism. The outer frame is integrally formed, including a base and two mirror frames. The outer frame also includes a lever mechanism, and the base has A longitudinal side plate and two transverse side plates, one end of the two transverse side plates is respectively connected to the lever mechanism through a first flexible hinge, the mirror frame is connected to the transverse side plate through the second flexible hinge, and connected to the horizontal side plate through the first flexible joint. The displacement amplification output end of the lever mechanism is connected, one end of the actuator mechanism is fixedly connected with the longitudinal side plate, and the other end is matched with the displacement input plate of the lever mechanism; The swinging movable pole plate and the first and second fixed pole plate assemblies that constitute the differential sensor are located under the reflector. The reflector can improve the anti-vibration and anti-shock ability, and at the same time, the overall height is small and the deflection angle is large.
Description
technical field [0001] The invention belongs to the field of fast control reflectors, in particular to a one-dimensional fast control reflector. Background technique [0002] The fast control mirror is a device that adjusts the mirror angle in real time under the control of the input electrical signal. It has the advantages of small size, fast speed, and high precision. It can realize high-frequency angle pointing, scanning, and stabilization. It is used in adaptive optical compensation, It has a wide range of applications in visual tracking, image stabilization, etc. [0003] The existing fast control mirrors mainly have two driving modes: voice coil motor drive and piezoelectric ceramic drive. Generally speaking, the former has a larger scanning angle but a lower resonance frequency, and the latter has a smaller scanning angle but a higher scanning frequency. [0004] CN103823302A discloses a one-dimensional fast control mirror, which is driven by piezoelectric ceramics, ...
