Embodiment Construction
[0016] The actuator 1 is a piezoelectric ceramic micro-displacement actuator produced by Suzhou Pante Electric Ceramics Technology Co., Ltd., which is a cuboid with a size of 5×5×36mm. The output displacement is proportional to the applied voltage, and the nominal voltage is 150V. , the maximum output displacement is 40μm. The base 2 is a mounting seat, four actuators are arranged on the bottom, and a two-stage fully flexible lever type displacement amplification mechanism is designed on the upper part of the base, and the output displacement of the actuator 1 is transmitted to the end of the lever by 6 to 10 times. The flexible mechanism 3 is four columnar support rods, and three layers of sheet-like flexible hinges are designed in the middle of the rods. The lens mount 4 is a fixed platform for the double-sided reflector 5, and four symmetrical convex smooth planes are designed on the front. The double-sided reflector 5 is a glass-ceramic lens with a thickness of 7 mm. The ...

The invention discloses a double-faced quick steering reflector structure. The double-faced quick steering reflector structure comprises a double-faced reflector, an actuator, a base, a flexible support, a lens mounting table and a displacement sensor. On application occasions of pointing tracking and transceiving coaxiality of light beams, angle compensation needs to be performed on the transmitted light beams during echo receiving, difficulties exist in synchronizing a transmitted scanning angle and a compensated echo angle by use of two pointing lens devices, however, the consistency of turning angles can be effectively guaranteed by use of two faces of the same lens, echo can effectively compensate for the transmitted angle, and angles received by a detector are relatively stable. The double-faced quick steering reflector structure has the advantages that pointing errors caused by transceiving coaxiality by use of the two light beam pointing lenses are greatly reduced, meanwhile, the mounting space can be saved, and operation and control are facilitated.
