Embodiment 1

[0038] A prism reflective collimator, the structure is as follows Figure 1~7 shown.

[0039] refer to figure 1 , 2 , the calibrator includes a display 1, and also includes a box 2, in which a camera 3 and a collimator 4 are arranged side by side, and a power module 7 is also arranged. The display 1 is connected to the camera 3, and the camera 3 and the collimator 4 are respectively connected to the power module 7.

[0040] The parallel lamp tube includes a lamp tube body 401, a reticle lighting lamp 402, a reticle 403 and a collimating lens 404. The collimator lens 404 is located at the bottom nozzle of the lamp tube body 401 directly below. The collimator 4 can produce a bright reticle for aiming at a target under a dark background.

[0041] The box body 2 is also provided with a first three-pronged prism 5 . The two ends of the first three-vertical prism 5 are respectively located directly below the adjacent parts of the camera 3 and the collimator 4, one end can rece...

Embodiment 2

[0054] Under the special requirement of the shape of the laser transmitter, the side of the calibrator described in Embodiment 1 can be turned downwards to work in a vertical state.

Embodiment 3

[0056] The collimator described in Embodiment 1 works in combination with the three-dimensional adjustment platform, which facilitates the placement and alignment of the measured laser transmitter 11 and improves work efficiency.

Abstract

The invention discloses a prismatic reflection type calibrator and relates to the technical field of inspection of parallelism of optical axes. The prismatic reflection type calibrator comprises a display and further comprises a box, wherein a camera and a collimator are arranged in the box in parallel; the camera is connected with the display; the collimator can generate bright cross division lines under a dark background; a first triple prism is arranged in the box and comprises three reflectors perpendicular to one another; one end of the first triple prism can receive light beams of the collimator projected from the right upper side, and the other end of the first triple prism can reflect the light beams into the camera in parallel; a laser incidence window is formed in a position, which faces the camera, of the box; a reflecting prism group is arranged outside the box and comprises an entrance port and an exit port; and the entrance port is aligned with the collimator. The prismatic reflection type calibrator disclosed by the invention is high in complete calibration accuracy, convenient to adjust and operate and reliable; and moreover, illumination and size requirements of the environment and site are not needed, and the production efficiency is greatly improved.

Description

technical field [0001] The invention relates to an optical axis parallelism inspection device for laser shooting training products, in particular to a prism reflective calibrator and a calibration method for calibrating or inspecting the parallelism between the laser emission axis direction of a laser transmitter and the optical axis direction of a sight. Background technique [0002] In laser combat training, a laser transmitter is installed on a weapon such as a gun or cannon, and its laser beam must be consistent with the line of sight (or sight), so that the laser can hit the aiming point. Therefore, usually the laser optical axis and the line of sight should be strictly adjusted to a parallel relationship, that is, the long-distance target can be accurately struck. [0003] In order to calibrate or check the parallelism of the two optical axes, it is usually used to hit the laser beam on the grid plate on the long-distance channel, and use the camera to observe the rela...
