It is understood that the angle and relative position of the objective lens 52 and the eyepiece lens 51 with respect to each other can be any angle and position that satisfies the optical imaging conditions. In this embodiment, a third optical element 603 for imaging may be further provided between the objective lens 52 and the eyepiece lens 51. The third optical element 603 may be selected from the group consisting of a wedge mirror, a negative lens, a roof prism, a half-pentaprism, and combinations thereof, and the specific structure thereof is not described herein.

The laser emitting device 30 is configured to emit a laser beam in a direction toward a target object. The laser light receiving device 40 is configured to receive a laser beam toward a target object. The laser emitting device 30 includes a laser emitter and a laser mirror at the front end of the laser emitter for collimating the laser light parallel to the horizontal plane. The laser light receiving device 40 includes a laser light receiver and a laser light receiving mirror. The laser receiving mirror is positioned at the front end of the laser receiver and is used for converging laser to the laser receiver. In the present embodiment, the optical path of the laser emitting device 30, the optical path of the laser receiving device 40, and the optical path of the imaging device 50 are independent of each other.

Preferably, the image stabilization system 10 is disposed on the front side of the objective lens 52 of the imaging device 50. In this embodiment, the image stabilizing system 10 includes an image stabilizing component 1 and a reflecting component 2 disposed at front ends of the laser emitting device 30, the laser receiving device 40 and the imaging device 50, where the image stabilizing component 1 is connected with the reflecting component 2, and the direction of the ranging light path is automatically corrected by automatically changing the direction of the reflecting component 2, so as to achieve the purpose of automatic image stabilization.

In this embodiment, the reflection assembly 2 includes at least a first reflection optical element 21 and a second reflection optical element 22 disposed opposite to each other. Preferably, the first reflective optical element 21 is connected to the image stabilizing assembly 1. The image stabilizing component 1 changes the direction of the ranging light path by adjusting the angle of the first reflecting optical element 21, so as to achieve the purpose of automatic image stabilization. In the present embodiment, the first reflective optical element 21 is disposed at an angle to the objective lens 52.

Preferably, the first reflective optical element 21 is disposed at a substantially 45 ° angle to the objective lens 52, with the upper end of the first reflective optical element 21 facing forward (i.e., relatively close to the target) and the lower end facing rearward (i.e., relatively far from the target). Thereby, the first reflective optical element 21 can convert the vertical light beam into the horizontal light beam to be emitted, or can convert the horizontal light beam into the vertical light beam to be emitted. Preferably, the first reflective optical element 21 is located within the range of the objective lens 52 along a projection in the vertical plane to ensure that all light reflected by the first reflective optical element 21 is emitted through the objective lens 52.

The reflective surface of the second reflective optical element 22 faces the reflective surface of the first reflective optical element 21. Preferably, the second reflective optical element 22 is located directly above the first reflective optical element 21. I.e. the projections of the first reflective optical element 21 and the second reflective optical element 22 coincide in the horizontal plane. Natural light emitted from the object is reflected sequentially by the second reflective optical element 22 and the first reflective optical element 21, then reaches the objective lens 52, and finally is imaged by the eyepiece 51. It is understood that the angles and relative positions of the first reflective optical element 21 and the second reflective optical element 22 with respect to each other may be any angle and position that satisfies the reflection condition. Preferably, the second reflective optical element 22 is fixedly arranged relative to the housing 20. In other embodiments, the image stabilizing device 1 may also be connected to the first reflective optical element 21 and the second reflective optical element 22, respectively, so that the steering directions of the first reflective optical element 21 and the second reflective optical element 22 are adjusted by the image stabilizing device 1, respectively.

In this embodiment, the first optical reflection optical element 21 and the second optical reflection element 22 are both mirrors, and the dimensions of the two mirrors are the same. In other embodiments, the first optical reflection optical element 2 and the second optical reflection element 22 may be prisms, or one of them is a prism, and the other is a mirror. In alternative embodiments, the reflective assembly 2 may also include a third or more reflective optical elements.

Fig. 4 schematically shows the optical path of the laser emitting device 30 and the optical path of the laser receiving device 40. The laser transmitter emits a laser beam having a certain specific wavelength band (for example, 905nm wavelength band), and the laser beam is collimated into a parallel laser beam after passing through the laser transmitter mirror, passes through the second reflective optical element 22, and then is directed to the target object, forming a laser transmission optical path. After reaching the target, the laser light is reflected, and part of the reflected laser light passes through the second reflecting optical element 22, then passes through the laser receiving mirror to form converged laser light, and then reaches the laser receiver positioned behind the laser receiving mirror to form a laser receiving light path. When the laser ranging is needed, the laser transmitter transmits laser, and the laser receiver converts an optical signal into an electric signal after receiving the laser reflected by the target object, and the measuring distance of the target object is obtained after processing.

Fig. 5 schematically shows an imaging optical path of the imaging device 50. The imaging light path formed by the imaging device 50 starts from the target, and natural light emitted from the target sequentially passes through the second reflective optical element 22 and the first reflective optical element 21, then reaches the objective lens 52, and finally reaches the eyepiece lens 51. It can be seen that the laser emission light path, the laser receiving light path and the natural light imaging light path of this embodiment are independent. In this embodiment, the image stabilizing component 1 of the image stabilizing system 10 can automatically change the direction of the first reflective optical element 21 of the reflective component 2 to automatically correct the direction of the imaging light path, so as to achieve the purpose of automatic image stabilization.

s2, monitoring the self posture of the laser ranging telescope by an image stabilizing control board 3; and

and S3, when the shake information collection and control unit of the image stabilizing control board 3 detects the posture change of the laser ranging telescope, the image stabilizing component 1 of the image stabilizing system 10 is controlled to perform front-back pitching adjustment and left-right rolling adjustment on the first reflecting optical element 21 so as to offset image blurring caused by shake.

In step S3, referring to fig. 2 and fig. 8 to fig. 10, when the shake information collection and control unit of the image stabilizing control board 3 detects the posture change of the laser ranging telescope, the cooperation among the base 11, the first mount 12 and the second mount 13 can enable the first reflective optical element 21 to move so as to compensate and correct the shake. Specifically, when the shake is detected, the first electromagnet 116 is energized, and the first magnetic core 211 can be attracted by the first electromagnet 116 to approach the first electromagnet 116, so as to drive the first mounting seat 12 to rotate relative to the base 11, at this time, the first elastic body 117 is stretched, and shake around the longitudinal direction is corrected under the cooperation of the first electromagnet 116 and the first elastic body 117; the second electromagnet 215 is electrified, and the second magnetic core 311 can be absorbed by the second electromagnet 215 to approach the second electromagnet 215, so as to drive the second mounting seat 13 to rotate relative to the first mounting seat 12, at this time, the second elastic body 222 is stretched, and shake around the transverse direction is corrected under the cooperation of the second electromagnet 215 and the second elastic body 222. Thereby, the corrected parallel light enters the imaging device 50.
