optical path 1 (laser emission, irradiation to object to be measured): the laser with the wavelength of 800nm provided by the laser module enters the sixth mirror housing 6, is reflected by the first reflector 8 with the angle of 45 degrees, and then is directionally diverged into the second mirror housing 2 right above the laser module by the negative lens 9, and after the light beam is reflected to the front group mirror 10 in the first mirror housing 1 from the surface A of the second reflector 11, the light beam is emitted to an object to be observed in a parallel manner, and in the light path 1, the light flux can be increased by the arrangement of the negative lens 9, so that the aperture of the invention is larger than that of the traditional distance measuring and sighting mirror.
Optical path 3 (laser signal return) and optical path 4 (laser signal reception): the observed object returns a laser signal after receiving light, the returned laser signal forms a converged light beam to the R reflecting surface of the middle group mirror 13 after passing through the front group mirror 10 in the first mirror housing 1, the R reflecting surface totally reflects the main wavelength of the laser emitted by the laser, but does not reflect light of other wavelengths such as visible light, then the converging angle is adjusted by the beam shape mirror 12 in the second mirror housing 2 to change the spatial position of the received signal, and the beam after beam shape is totally reflected by the B surface of the second mirror 11 and converged at the position of the signal receiving point.
Optical path 2 (object imaging): after receiving light, the object to be observed reflects a part of the laser beam, and the reflected part of the laser beam reaches the R surface of the middle group mirror 13 in synchronization with the return laser signal, and since the R surface reflects only the main wavelength of the laser beam and can enhance the transmission of visible light, the reflected part of the laser beam and the visible light are transmitted through the R surface of the middle group mirror 13 and then are converged on the image plane by the rear group mirror 14, thereby increasing the image side diameter.

Example 2
In the aspect of astronomical telescope application, the R reflecting surfaces of the middle group of mirrors of the invention are as follows: on one hand, the R surface is directly a reflecting surface and is used for totally reflecting light with the dominant wavelength (for example 855nm) emitted by the laser; on the other hand, the light transmittance of the light except the main wavelength in the range of 430-1100nm can be increased, and the night vision capability can be improved.
