[0003] Currently, the optical path is usually changed by using a motor to drive the reflector to move back and forth on a specified guide rail. The existing optical path change method is difficult to achieve rapid optical path change due to the limitation of the inertia of the mechanical structure, which limits the optical measurement speed based on optical path change.

[0006] The beneficial effect of the utility model is that since the cam light-transmitting mirror can realize rapid rotation, under different rotation angles, the distance of light traveling back and forth between the cam light-transmitting mirror and the change of the air optical path causes a dynamic change of the total optical path, so the method can realize rapid change of the optical path.
[0007] On the basis of the above technical solution, the present invention can also be improved as follows.

[0029] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.
[0030] Example 1
[0031] like Figure 1-2 As shown, the cam light transmitting mirror 300 has a plurality of sector plates 310, and the plurality of sector plates 310 form a plurality of concentric circles. The lens rod 100 is arranged on one side of the cam light transmitting mirror 300, and the reflector 500 is arranged on the other side of the cam light transmitting mirror 300. The lens rod 100, the center 330 of the cam light transmitting mirror 300, and the reflector 500 are arranged in a straight line. Light is emitted from the lens rod 100, and the emission direction of the center of the light is perpendicular to the sector plate 310, passes through the sector plate 310 and is transmitted to the center 330. The light passes through the surface of the sector plate 310 on the other side of the cam light transmitting mirror 300 and is emitted to the reflector 500, and then the light returns to the lens rod 100 in the opposite direction.
[0032] Specifically, since the cam light-transmitting mirror 300 can achieve rapid rotation, under different rotation angles, the total optical path is dynamically changed due to the change in the distance of light traveling back and forth from the cam light-transmitting mirror 300 and the air optical path, so the method can achieve rapid change of the optical path. In this embodiment, the cam light-transmitting mirror 300 is processed as an integrated light-transmitting mirror. In this embodiment, the surface of the cam light-transmitting mirror 300 is processed into a plurality of fan shapes. In this embodiment, the lens rod 100 adopts a self-focusing lens rod. Alternatively, the lens rod can also be replaced by other optical elements having the same effect as the self-focusing lens rod.
[0033] like Figure 1-2 As shown, the radius of the plurality of sector plates 310 is the same, the thickness of the plurality of sector plates 310 is the same, and the central angle of the plurality of sector plates 310 is the same.
[0034] Specifically, the light beam is emitted from the lens rod 100 to the cam light transmitting mirror 300, is incident on the center of the cam light transmitting mirror 300 through the fan-shaped plate 310 on one side of the cam light transmitting mirror 300, and is emitted to the reflector 500 through the fan-shaped plate 310 on the other side of the cam light transmitting mirror 300. Then, the reflected light beam is incident on the cam light transmitting mirror 300 from the fan-shaped plate 310 on one side, passes through the center of the cam light transmitting mirror 300, and is emitted to the lens rod 100 through the fan-shaped plate 310 on the other side of the cam light transmitting mirror 300.
[0035] like Figure 1-2 As shown, the cam light transmitting mirror 300 rotates with the same center 330 of the plurality of sector plates 310 as a rotation point.
[0036] Specifically, the centers 330 of the plurality of sector plates 310 are the same center 330. When the cam light transmitting mirror 300 rotates, the light beam is emitted from the lens rod 100 to the cam light transmitting mirror 300, is incident on the center of the cam light transmitting mirror 300 from the sector plate 310 on one side of the cam light transmitting mirror 300, and is emitted to the reflector 500 from the sector plate 310 on the other side of the cam light transmitting mirror 300. Then, the reflected light beam is incident on the cam light transmitting mirror 300 from the sector plate 310 on one side, passes through the center of the cam light transmitting mirror 300, and is emitted to the lens rod 100 from the sector plate 310 on the other side of the cam light transmitting mirror 300. It can be ensured that the light is always vertically incident on the sector plate 310 of the cam light transmitting mirror 300. To ensure the parallelism of incident light and reflected light, the reflector 500 is designed to be perpendicular to the light, the light emitted by the lens rod 100 is designed to pass through the rotation center of the cam mirror 300, and the centers of the fan-shaped plates 310 on the lens are all rotation centers, which theoretically ensures that the incident light enters the lens perpendicularly.
[0037] like Figure 1-2 As shown, the cam light-transmitting mirror 300 is made of a highly light-transmitting material.
[0038] Specifically, the cam light-transmitting mirror 300 is made of a highly light-transmitting material, the material inside the lens is uniform, and the light propagates along a straight line in the uniform material, ensuring that the incident light and the light returned from the lens are parallel. In this embodiment, the cam light-transmitting mirror 300 is made of optical glass, and alternatively, the cam light-transmitting mirror 300 can also be made of other materials with a highly light-transmitting effect.
[0039] like Figure 1-2 As shown, a counterweight wheel 700 is further arranged above or below the cam light transmissive mirror 300 , and the axis of the counterweight wheel 700 and the axis of the cam light transmissive mirror 300 are synchronously rotating axes, and the counterweight wheel 700 and the cam light transmissive mirror 300 rotate synchronously.
[0040] Specifically, the axis of the counterweight wheel 700 and the axis of the cam mirror 300 are synchronously rotating axes. When the counterweight wheel 700 and the cam mirror 300 rotate synchronously, the synchronously rotating axes can generate reverse vibration force, thereby reducing the vibration of the cam mirror 300 caused by eccentricity during rotation.
[0041] like Figure 1-2 As shown, the center of the counterweight wheel 700 is vertically installed with the rotation center 330 of the cam light transmitting mirror 300 as the axis.
[0042] Specifically, the center of the counterweight wheel 700 is vertically installed with the rotation center 330 of the cam mirror 300 as the axis, so that the axis of the counterweight wheel 700 and the axis of the cam mirror 300 are synchronous rotating axes, so that the synchronous rotating axes can generate reverse vibration force, thereby reducing the vibration of the cam mirror 300.
[0043] The beneficial effects of this embodiment are as follows: the light beam is emitted from the lens rod 100 to the cam light mirror 300, is incident on the center of the cam light mirror 300 through the fan-shaped plate 310 on one side of the cam light mirror 300, and is emitted to the reflector 500 through the fan-shaped plate 310 on the other side of the cam light mirror 300. Then, the reflected light beam is incident on the cam light mirror 300 from the fan-shaped plate 310 on one side, passes through the center of the cam light mirror 300, and is emitted to the lens rod 100 through the fan-shaped plate 310 on the other side of the cam light mirror 300. It is ensured that the incident and emitted light beams of the same beam are parallel. Since the cam light mirror 300 can be rotated quickly, under different rotation angles, the total optical path is dynamically changed due to the change in the distance of the light traveling back and forth from the cam light mirror 300 and the air optical path, so this method can achieve a rapid change in the optical path.
[0044] The working process of this embodiment is as follows: the light beam is emitted from the lens rod 100 to the cam light transmitting mirror 300, is incident on the center of the cam light transmitting mirror 300 through the fan-shaped plate 310 on one side of the cam light transmitting mirror 300, and is emitted to the reflector 500 through the fan-shaped plate 310 on the other side of the cam light transmitting mirror 300. Then, the reflected light beam is incident on the cam light transmitting mirror 300 from the fan-shaped plate 310 on one side, passes through the center of the cam light transmitting mirror 300, and is emitted to the lens rod 100 through the fan-shaped plate 310 on the other side of the cam light transmitting mirror 300.

[0069] like Figure 1-2As shown, a counterweight wheel 700 is further arranged above or below the cam light transmissive mirror 300 , and the axis of the counterweight wheel 700 and the axis of the cam light transmissive mirror 300 are synchronously rotating axes, and the counterweight wheel 700 and the cam light transmissive mirror 300 rotate synchronously.
[0070] Specifically, the axis of the counterweight wheel 700 and the axis of the cam mirror 300 are synchronously rotating axes. When the counterweight wheel 700 and the cam mirror 300 rotate synchronously, the synchronously rotating axes can generate reverse vibration force, thereby reducing the vibration of the cam mirror 300 caused by eccentricity during rotation.
[0071] like Figure 1-2 As shown, the center of the counterweight wheel 700 is vertically installed with the rotation center 330 of the cam light transmitting mirror 300 as the axis.
[0072] Specifically, the center of the counterweight wheel 700 is vertically installed with the rotation center 330 of the cam mirror 300 as the axis, so that the axis of the counterweight wheel 700 and the axis of the cam mirror 300 are synchronous rotating axes, so that the synchronous rotating axes can generate reverse vibration force, thereby reducing the vibration of the cam mirror 300.
[0073] The beneficial effects of this embodiment are as follows: the light beam is emitted from the lens rod 100 to the cam light mirror 300, is incident on the center of the cam light mirror 300 through the fan-shaped plate 310 on one side of the cam light mirror 300, and is emitted to the reflector 500 through the fan-shaped plate 310 on the other side of the cam light mirror 300. Then, the reflected light beam is incident on the cam light mirror 300 from the fan-shaped plate 310 on one side, passes through the center of the cam light mirror 300, and is emitted to the lens rod 100 through the fan-shaped plate 310 on the other side of the cam light mirror 300. It is ensured that the incident and emitted light beams of the same beam are parallel. By using an irregular light mirror, when the cam light mirror 300 rotates rapidly, different rotation angles will be formed, so that the distance of the light traveling back and forth from the cam light mirror 300 and the air optical path will change, resulting in a dynamic change in the total optical path. The centers 330 of the multiple sector plates 310 with different radii are the same center 330 , which can ensure that the light is always incident vertically on the sector plate 310 of the cam light transmitting mirror 300 .
[0074] The working process of this embodiment is as follows: the light beam is emitted from the lens rod 100 to the cam light transmitting mirror 300, is incident on the center of the cam light transmitting mirror 300 through the fan-shaped plate 310 on one side of the cam light transmitting mirror 300, and is emitted to the reflector 500 through the fan-shaped plate 310 on the other side of the cam light transmitting mirror 300. Then, the reflected light beam is incident on the cam light transmitting mirror 300 from the fan-shaped plate 310 on one side, passes through the center of the cam light transmitting mirror 300, and is emitted to the lens rod 100 through the fan-shaped plate 310 on the other side of the cam light transmitting mirror 300.
[0075] Example 4
[0076] like Figure 1-2 As shown, the cam light transmitting mirror 300 has a plurality of sector plates 310, and the plurality of sector plates 310 form a plurality of concentric circles. The lens rod 100 is arranged on one side of the cam light transmitting mirror 300, and the reflector 500 is arranged on the other side of the cam light transmitting mirror 300. The lens rod 100, the center 330 of the cam light transmitting mirror 300, and the reflector 500 are arranged in a straight line. Light is emitted from the lens rod 100, and the emission direction of the center of the light is perpendicular to the sector plate 310, passes through the sector plate 310 and is transmitted to the center 330. The light passes through the surface of the sector plate 310 on the other side of the cam light transmitting mirror 300 and is emitted to the reflector 500, and then the light returns to the lens rod 100 in the opposite direction.
[0077] Specifically, since the cam light-transmitting mirror 300 can achieve rapid rotation, under different rotation angles, the total optical path is dynamically changed due to the change in the distance of light traveling back and forth from the cam light-transmitting mirror 300 and the air optical path, so the method can achieve rapid change of the optical path. In this embodiment, the cam light-transmitting mirror 300 is processed as an integrated light-transmitting mirror. In this embodiment, the surface of the cam light-transmitting mirror 300 is processed into a plurality of fan shapes. In this embodiment, the lens rod 100 adopts a self-focusing lens rod. Alternatively, the lens rod can also be replaced by other optical elements having the same effect as the self-focusing lens rod.
[0078] like Figure 1-2 As shown, the radii of the plurality of sector plates 310 are different, the thicknesses of the plurality of sector plates 310 are different, and the central angles of the plurality of sector plates 310 are different.
[0079] Specifically, the light beam is emitted from the lens rod 100 to the cam light transmitting mirror 300, is incident on the center of the cam light transmitting mirror 300 through the fan-shaped plate 310 on one side of the cam light transmitting mirror 300, and is emitted to the reflector 500 through the fan-shaped plate 310 on the other side of the cam light transmitting mirror 300. Then, the reflected light beam is incident on the cam light transmitting mirror 300 from the fan-shaped plate 310 on one side, passes through the center of the cam light transmitting mirror 300, and is emitted to the lens rod 100 through the fan-shaped plate 310 on the other side of the cam light transmitting mirror 300. It is ensured that the incident and emitted light beams of the same light beam are parallel.
[0080] like Figure 1-2 As shown, the cam light transmitting mirror 300 rotates with the same center 330 of the plurality of sector plates 310 as a rotation point.
[0081] Specifically, the centers 330 of the plurality of sector plates 310 are the same center 330. When the cam light transmitting mirror 300 rotates, the light beam is emitted from the lens rod 100 to the cam light transmitting mirror 300, is incident on the center of the cam light transmitting mirror 300 from the sector plate 310 on one side of the cam light transmitting mirror 300, and is emitted to the reflector 500 from the sector plate 310 on the other side of the cam light transmitting mirror 300. Then, the reflected light beam is incident on the cam light transmitting mirror 300 from the sector plate 310 on one side, passes through the center of the cam light transmitting mirror 300, and is emitted to the lens rod 100 from the sector plate 310 on the other side of the cam light transmitting mirror 300. It can be ensured that the light is always vertically incident on the sector plate 310 of the cam light transmitting mirror 300. To ensure the parallelism of incident light and reflected light, the reflector 500 is designed to be perpendicular to the light, the light emitted by the lens rod 100 is designed to pass through the rotation center of the cam mirror 300, and the centers of the fan-shaped plates 310 on the lens are all rotation centers, which theoretically ensures that the incident light enters the lens perpendicularly.
[0082] like Figure 1-2 As shown, the cam light-transmitting mirror 300 is made of a highly light-transmitting material.
[0083] Specifically, the cam light-transmitting mirror 300 is made of a highly light-transmitting material, the material inside the lens is uniform, and the light propagates along a straight line in the uniform material, ensuring that the incident light and the light returned from the lens are parallel. In this embodiment, the cam light-transmitting mirror 300 is made of optical glass, and alternatively, the cam light-transmitting mirror 300 can also be made of other materials with a highly light-transmitting effect.
[0084] like Figure 1-2 As shown, a counterweight wheel 700 is further arranged above or below the cam light transmissive mirror 300 , and the axis of the counterweight wheel 700 and the axis of the cam light transmissive mirror 300 are synchronously rotating axes, and the counterweight wheel 700 and the cam light transmissive mirror 300 rotate synchronously.
[0085] Specifically, the axis of the counterweight wheel 700 and the axis of the cam mirror 300 are synchronously rotating axes. When the counterweight wheel 700 and the cam mirror 300 rotate synchronously, the synchronously rotating axes can generate reverse vibration force, thereby reducing the vibration of the cam mirror 300 caused by eccentricity during rotation.
[0086] like Figure 1-2 As shown, the center of the counterweight wheel 700 is vertically installed with the rotation center 330 of the cam light transmitting mirror 300 as the axis.
[0087] Specifically, the center of the counterweight wheel 700 is vertically installed with the rotation center 330 of the cam mirror 300 as the axis, so that the axis of the counterweight wheel 700 and the axis of the cam mirror 300 are synchronous rotating axes, so that the synchronous rotating axes can generate reverse vibration force, thereby reducing the vibration of the cam mirror 300.
[0088] The beneficial effects of this embodiment are as follows: the light beam is emitted from the lens rod 100 to the cam light mirror 300, is incident on the center of the cam light mirror 300 through the fan-shaped plate 310 on one side of the cam light mirror 300, and is emitted to the reflector 500 through the fan-shaped plate 310 on the other side of the cam light mirror 300. Then, the reflected light beam is incident on the cam light mirror 300 from the fan-shaped plate 310 on one side, passes through the center of the cam light mirror 300, and is emitted to the lens rod 100 through the fan-shaped plate 310 on the other side of the cam light mirror 300. It is ensured that the incident and emitted light beams of the same beam are parallel. By using an irregular light mirror, when the cam light mirror 300 rotates rapidly, different rotation angles will be formed, so that the distance of the light traveling back and forth from the cam light mirror 300 and the air optical path will change, resulting in a dynamic change in the total optical path. The centers 330 of the multiple sector plates 310 with different radii are the same center 330 , which can ensure that the light is always incident vertically on the sector plate 310 of the cam light transmitting mirror 300 .
[0089] The working process of this embodiment is as follows: the light beam is emitted from the lens rod 100 to the cam light transmitting mirror 300, is incident on the center of the cam light transmitting mirror 300 through the fan-shaped plate 310 on one side of the cam light transmitting mirror 300, and is emitted to the reflector 500 through the fan-shaped plate 310 on the other side of the cam light transmitting mirror 300. Then, the reflected light beam is incident on the cam light transmitting mirror 300 from the fan-shaped plate 310 on one side, passes through the center of the cam light transmitting mirror 300, and is emitted to the lens rod 100 through the fan-shaped plate 310 on the other side of the cam light transmitting mirror 300.

The lens rod 100, the center 330 of the cam light transmitting mirror 300, and the reflector 500 are arranged in a straight line. Light is emitted from the lens rod 100, and the emission direction of the center of the light is perpendicular to the sector plate 310, passes through the sector plate 310 and is transmitted to the center 330. The light passes through the surface of the sector plate 310 on the other side of the cam light transmitting mirror 300 and is emitted to the reflector 500, and then the light returns to the lens rod 100 in the opposite direction.
[0092] Specifically, since the cam light-transmitting mirror 300 can achieve rapid rotation, under different rotation angles, the total optical path is dynamically changed due to the change in the distance of light traveling back and forth from the cam light-transmitting mirror 300 and the air optical path, so the method can achieve rapid change of the optical path.

Then, the reflected light beam is incident on the cam light transmitting mirror 300 from the fan-shaped plate 310 on one side, passes through the center of the cam light transmitting mirror 300, and is emitted to the lens rod 100 through the fan-shaped plate 310 on the other side of the cam light transmitting mirror 300.

[0100] Specifically, the axis of the counterweight wheel 700 and the axis of the cam mirror 300 are synchronously rotating axes. When the counterweight wheel 700 and the cam mirror 300 rotate synchronously, the synchronously rotating axes can generate reverse vibration force, thereby reducing the vibration of the cam mirror 300 caused by eccentricity during rotation.
