This feature can ensure that the adjustment results of each dimension are not coupled with each other, greatly improving the precision and accuracy of posture adjustment; in addition, six-dimensional reciprocating and large-stroke continuous and smooth adjustment can be achieved through driving threads, and point contact is maintained during the adjustment process. Compared with the previous surface contact guide rail form, the influence of track processing accuracy on adjustment accuracy is greatly reduced.

[0061] In addition, the embodiment of the present application further provides an optical six-dimensional posture adjustment method, which is applied to the optical six-dimensional posture adjustment device provided in any of the above embodiments, such as Figure 5 As shown, Figure 5 A rotation schematic diagram of an optical six-dimensional posture adjustment provided in an embodiment of the present application includes adjusting X-axis rotation, adjusting Y-axis rotation, and adjusting Z-axis rotation. Based on this, the optical six-dimensional posture adjustment method includes: adjusting the height of the lens through the Z-axis displacement component, adjusting the longitudinal displacement of the lens through the Y-axis displacement component, and adjusting the lateral displacement of the lens through the X-axis displacement component; adjusting the deflection angle of the lens through the Z-axis rotation component, adjusting the inclination angle of the lens through the Y-axis rotation component, and adjusting the pitch angle of the lens through the X-axis rotation component.

[0062] Specifically, the lens can be pushed to deflect by rotating the Z-axis rotation adjustment thread pair, and after the adjustment, the position can be fixed by the locking screw. The lens can be pushed to tilt by rotating the Y-axis rotation adjustment thread pair, and after the adjustment, the position can be fixed by the locking screw. The lens can be pushed to pitch by rotating the X-axis rotation adjustment thread pair, and after the adjustment, the position can be fixed by the locking screw.

[0063] It should be noted that the above displacement adjustment processes do not interfere with each other and can be adjusted in any order as needed.

[0064] In some optional embodiments, the adjustment accuracy of the method can be calculated based on the change of the screw from position 1 to position 2 by rotating the thread pair, as well as the pitch of the corresponding thread pair, the distance between the thread pair vertex and the fulcrum, and the rotation angle.
