Referring to fig. 6, an embodiment of the present disclosure provides a schematic diagram of a triangular prism and an adjustment platform in an optical path system. As shown in the figure, the third adjusting device can be used to adjust the position and/or angle of the triangular prism, so that the light reflected by the first reflective mirror and the second reflective mirror can form a clear and accurate virtual image after passing through the mirror surface of the triangular prism.
In an implementation, the third adjusting device may include a fixed bracket, a rotating platform, and an adjusting platform, and the adjusting platform may further include two buttons for XY axial adjustment. The triangular prism can be fixed in the fixed support, the fixed support can be installed in the rotating platform, and the rotating platform can be installed in the adjusting platform.
The adjusting platform can adjust the position of the triangular prism and the fixed support within the adjusting range of +/-6.5 mm in the X-axis direction through the adjusting platform X-direction adjusting button, the adjusting platform can adjust the position of the triangular prism and the fixed support within the adjusting range of +/-6.5 mm in the Y-axis direction through the adjusting platform Y-direction adjusting button, and the angle of the triangular prism and the fixed support can be adjusted through the adjusting triangular prism rotating platform.
Therefore, by the fixing method, the adjusting device is matched with the 13mm equidistant array-type fixing position (such as threaded holes) on the fixing bottom plate, so that the random relative space position adjustment between the triangular prism and the fixing bottom plate in the optical path system can be realized.
