Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings and preferred examples.

[0021] The calibration method provided by the preferred embodiment of the present invention includes the following steps:

[0022] The first step, according to figure 1 Set up the adjustment device as shown. First, place the combined image level on the adjustable platform 1, and adjust the knob on the base 5 of the adjustable platform 1 to center the bubble of the combined image level; fix the reflector 6 on the Dove prism assembly without the Dove prism ( That is, the incident end of the Dove prism), the transmitting source theodolite 3 is aligned with the incident end of the Dove prism assembly, and the receiving source theodolite 4 is aligned with the exit end of the Dove prism assembly.

[0023] The adjustable platform 1 is a two-dimensional adjustable platform, which can be adjusted in both axial and radial directions. Both the ...

Abstract

The invention discloses a method for adjusting the parallelism of an axis of a reflector and a mechanical rotating shaft of a Dove prism. The method comprises the following steps of adjusting an emitter theodolite to be parallel with the mechanical rotating shaft of a Dove prism component; adjusting a receiver theodolite to be in the same optical axis as the emitter theodolite; and adjusting eight screws for fixing the Dove prism on the Dove prism component to make the axis of the reflector of the Dove prism parallel with the mechanical rotating shaft of the Dove prism. The method has the characteristic that debugging instruments are simple in structures, simple and convenient to erect and adjust, and high in operability, a large amount of time for assembling a product is saved, the work efficiency of an operator is improved, and the method can be widely applied to adjusting the parallelism of the optical axis of the reflector and the mechanical rotating shaft of the Dove prism.

Description

technical field [0001] The invention belongs to the field of optical machine assembly and adjustment, and mainly relates to an optical component adjustment method, in particular to an adjustment method for realizing that the axis of the reflective surface of a Dove prism is parallel to the axis of mechanical rotation. Background technique [0002] Zhoushi photoelectric observation and aiming system can realize the observer's search, observation, aiming and tracking of external targets by rotating the head reflector assembly. However, since the observation field of view and sighting system rotates with the azimuth during use, the observation image also rotates accordingly, resulting in a phenomenon that the observation image is inconsistent with the actual target. In order to eliminate this phenomenon, generally add an image elimination prism in the optical path of the system, so that the image can be reversely rotated to eliminate this effect. Dove prisms are commonly used ...
