[0002] In the plane, the outgoing light direction of the conventional dihedral mirror does not change with the swing of the mirror assembly, and will remain parallel (as shown figure 1 ); in the three-dimensional space, the cube-corner prism can direct the incident light back, and the incident light and the outgoing light are in a parallel state, and are not affected by the shaking posture of the prism (as shown figure 2 ), the corner cube prism has a large number of applications in engineering technology; the optical sighting device is a kind of optical lens imaging, and the target image is refracted to the specified display plane through the above-mentioned dihedral mirror and cube corner cube prism; Sighting equipment is a kind of optical sighting equipment, which is installed on some special-purpose vehicles to meet the needs of these vehicles to observe and aim at the target while moving, but the current vehicle-mounted optical sighting equipment is in this It is still difficult to obtain stable and reliable observation results in the application environment where the vehicle is shaking, so when using the current vehicle-mounted optical sighting equipment, it is still necessary to stop the vehicle first and then measure;

[0003] In response to this problem, many research units have also carried out relevant technical research, for example: "Research and Design of Vehicle-mounted Real-time Video Stabilization System" published by China North Vehicle Research Institute on "Computer Measurement and Control" 2007.15 (7), page 922 , the design uses multiple electronic control technologies such as electronic image stabilization, inertial technology image stabilization and video image stabilization to achieve image stabilization for motion viewing and aiming. This design requires a large number of electronic components to work together, with complex structure, high cost, and manufacturing process The level requirements are also very high
