Embodiment Construction

[0041] The invention provides a method for adjusting the collimation difference of a horizon-type theodolite, which solves the problem that the machining accuracy of mechanical structural parts in the horizon-type theodolite is difficult to meet the precision requirements of the optical system, resulting in the inclination or eccentricity of the visual axis and the optical axis.

[0042] Such as figure 1 , figure 2 with Figure 4 As shown, the horizon type theodolite mainly includes a U-shaped frame 1, a large box body 2 installed on the U-shaped frame 1, a primary mirror 3 and a secondary mirror mirror group 4 installed at both ends of the large box body 2, and a large box body 2 installed on the large box body 2. The primary mirror trimming pad 5 between the primary mirror mirror group 3 and the secondary mirror trimming pad 6 for adjusting the posture of the primary mirror mirror group and the secondary mirror mirror group between the large box 2 and the secondary mirror ...

Abstract

The present invention belongs to the technical field of optics, and particularly relates to a horizon type theodolite collimation error adjustment method, which mainly comprises: 1) adjusting the auto-collimating centering of a main mirror; 2) adjusting the lens auto-collimating centering of a CCD; and 3) installing a sub-mirror assembly, eliminating the coma and the astigmatism between the main mirror assembly and the sub-mirror assembly, and ensuring that the spherical aberration and the focal distance of the main mirror system and the sub-mirror system meet the requirements. According to the present invention, the operation of the method is simple, and the problem that the processing precision of the mechanical structure member in the horizon type theodolite difficultly meets the optical system precision requirement so as to cause the inclination or decentration of the visual axis and the optical axis is solved.

Description

technical field [0001] The invention belongs to the field of optical technology, and in particular relates to a method for adjusting the collimation difference of a horizon-type theodolite. Background technique [0002] Since the processing and assembly precision of the parts is difficult to meet the precision requirements of the optical system, when the horizontal axis of the horizontal theodolite rotates through 180°, the angle between the positions in the horizontal plane before and after the rotation of the visual axis is not 180°. Such as figure 1 As shown, O is the intersection of the visual axis and the horizontal axis. OZ is the ideal boresight position in the mirror state, OZ 1 is the actual boresight position of the positive mirror, and their included angle ∠ZOZ 1 That is the collimation difference C, OZ' 2 It is the actual visual axis position when the mirror is inverted, and the angle between it and the OZ axis is (180°+C). After the azimuth axis of the inst...
