The base 100 may be a plate structure, and its shape may be rectangular, circular, etc. The base 100 is provided with a light outlet 110. One end of the first mounting seat 200 is rotatably connected with the base 100, and a first plane mirror 210 is disposed on the first mounting seat 200. The second mount 300 is connected to the other end of the first mount 200, the second mount 300 is rotatable about a first axis (C axis in fig. 4) with respect to the first mount 200, and the second mount 300 is provided with a second plane mirror 310.

The third mount 400 is connected to an end of the second mount 300 remote from the first mount 200, the third mount 400 is capable of rotating about a second axis (D axis in fig. 4) perpendicular to the first axis with respect to the second mount 300, a third plane mirror 410 is disposed on the third mount 400, and a light inlet 420 is further disposed on a side of the third mount 400 opposite to the third plane mirror 410.

The flat mirrors used in this application, such as the first flat mirror 210, the second flat mirror 310, and the third flat mirror 410, are required to be very flat, i.e., the flat surface shape accuracy of each flat mirror is high, for example, the surface shape accuracy is up to 1/10 wavelength, wherein 1 wavelength is 650nm.

In use, the base 100 may be mounted horizontally on a tripod or a support platform as shown in connection with fig. 5. It should be noted that, the light is emitted perpendicularly from the light outlet 110, which is related to the installation state of the optical device, specifically, the light is emitted along the direction perpendicular to the plane of the light outlet 110. If the plane in which the light outlet 110 is located is a horizontal plane, that is, the base 100 of the optical device of the present application is horizontally disposed or is disposed near horizontally, the light is emitted in a direction perpendicular to the horizontal plane, or the light is emitted in a vertical direction (near vertical direction).

When the angle of the first plane mirror 210 needs to be finely adjusted, the adjusting lever can be slid along the adjusting chute to adjust the angle of the first plane mirror 210.

Similarly, the second plane mirror 310 and the third plane mirror 410 are mounted to achieve fine adjustment of the angle, considering that the final light needs to exit as vertically as possible. In this application, the second mount 300 is provided with a second mirror mounting plate 320, and the second mirror 310 is floatably mounted on the second mirror mounting plate 320. The third mount 400 is provided with a third mirror mounting plate 430, and the third flat mirror 410 is floatably mounted on the third mirror mounting plate 430.

And the light inlet 420 is aligned with the observation target by adjusting the angle by which the third mount 400 rotates about the second axis (D axis). Therefore, when the observation target is tracked, only the angular speed of the second mounting seat 300 rotating around the first axis is the same as that of the earth, and the directions are opposite (from east to west), so that the influence of the earth rotation on the observation target can be eliminated, the observation target is always in the observation range of the optical device, and the third mounting seat 400 does not need to rotate relative to the second mounting seat 300 in the whole process of tracking the target.

through the third plane mirror 410, the second plane mirror 310, and the first plane mirror 210 sequentially disposed on the light transmission path, light can be transmitted to a preset constant direction so that a user can observe and observe a target. Meanwhile, since the second mount 300 where the second plane mirror 310 is located can rotate around the axis parallel to the rotation axis of the earth, after each component is adjusted and the observation target is located in the observation range, the influence of the earth rotation on the observation target can be eliminated only by rotating the second mount 300 at a preset angular velocity and direction, and the observation target is always located in the observation range of the optical device. And the third mount 400 does not need to be rotated relative to the second mount 300 during the whole process of tracking the target, i.e. the angle of the third plane mirror 410 does not need to be adjusted at any time. Compared with the traditional observation device, the angle of the two plane mirrors needs to be adjusted at any time according to the position change of the observation target, and the optical device is more convenient and reliable to use.

By providing the angle adjuster 500 and the mounting base plate 800, it is possible to facilitate adjustment of the pitch angle and the horizontal azimuth angle of the first axis so that the first axis is parallel to the earth rotation axis, so as to achieve automatic tracking of the observation target.

By providing the first drive assembly 600 and the second drive assembly 700, the optical device is enabled to achieve automatic angular adjustment and automatic tracking of the observed target. By arranging the first detection component and the second detection component, the rotatable part can be reset to the initial position when the optical device is started, so that the components can be conveniently adjusted to track and observe the target star.

By providing the first plane mirror 210, the second plane mirror 310 and the third plane mirror 410 with fine-tuning structures, the defect that the optical device cannot guarantee absolute level in actual use can be overcome, and the light can be ensured to be nearly vertical as far as possible when exiting from the light outlet 110.

The above embodiments are merely illustrative of structures, and the structures in the embodiments are not fixedly matched and combined structures, and in the case of no structural conflict, the structures in the embodiments can be arbitrarily combined for use.

While the utility model has been described with reference to several exemplary embodiments, it is to be understood that the terminology used is intended to be in the nature of words of description and of limitation. As the present utility model may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described embodiments are not limited by any of the details of the foregoing description, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalences of such meets and bounds are therefore intended to be embraced by the appended claims.
