Description

Technical Field

[0001] The utility model relates to the technical field of photoelectric collimators, in particular to an angle detection and correction mechanism for photoelectric collimators. Background Art

[0002] The photoelectric collimator is an instrument that uses the principle of self-collimation of light to detect and correct angle deviation. Its basic working principle is: the light emitted by the light source passes through the graticule and passes through the objective lens to become a beam of light parallel to the optical axis. When the reflector is perpendicular to the optical axis, the light returns to the original path after reflection and re-converges on the graticule to form an image. If the reflector is at a certain angle α to the optical axis, the reflected light forms an angle of 2α with the original light. The angle α can be inversely calculated by measuring the offset.

[0003] An existing Chinese patent (publication number: CN203231737U) discloses a photoelectric autocollimator, comprising: a light source, a condenser, a graticule, a dichroic prism, a zoom telephoto objective lens group, a reflector and a receiver, wherein the zoom telephoto objective lens group comprises a front fixed group, a rear fixed group and a zoom group, the graticule is located directly above the dichroic prism, the condenser is located directly above the graticule, the light source is located directly above the condenser, the zoom telephoto objective lens group and the reflector are located on one side of the dichroic prism, and the receiver is located on the other side of the dichroic prism.

[0004] The above technical solution adopts a variable focal length telephoto objective lens group. When used for angle measurement or optical path alignment, the continuously zooming telephoto objective lens group can meet the measurement requirements of continuously adjustable measurement range, especially large angle measurement. However, no correction component is provided, and users may need to manually adjust and align, which not only increases the complexity of operation, but may also lead to operational errors, thereby affecting the stability and repeatability of the measurement results. In addition, a photoelectric collimator without a correction component may require more frequent calibration and maintenance, which will increase long-term operating costs. Therefore, we propose an angle detection and correction mechanism for a photoelectric collimator. Utility Model Content
