Embodiment Construction

[0013] refer to Figure 1 to Figure 4 Describe the embodiment of the present invention in detail. In this embodiment, an infrared laser-assisted alignment structure based on a movable spherical joint, the infrared laser collimator b is fixed in the main body c, and the spherical joint d is placed on the back cover a and In the spherical cavity between the main body c, the back cover a and the main body c are fixed. It can be seen that the laser light e is fixed in the circular groove in the spherical joint d; there is a gap between the spherical joint d and the spherical cavity where it is located, and it can rotate freely; it can be seen Laser e is a green laser.

[0014] Under the condition of long-distance alignment of the infrared laser in wireless laser communication, by introducing a spherical joint structure, an auxiliary alignment laser that does not overlap with the infrared laser is set at the infrared laser emitting end, and the position of the emitting end can be a...

Abstract

The invention relates to an infrared laser auxiliary alignment structure based on a movable spherical joint, and belongs to the technical field of wireless optical communication. The infrared laser collimator is fixed in the main body, the spherical joint is placed in a spherical cavity between the rear cover and the main body, the rear cover is fixedly connected with the main body, and the visible laser is fixed in a circular groove in the spherical joint. The device has the advantages that the structure is simple, the emitting angle of the visible laser can be adjusted in the vertical and horizontal range by adopting the spherical joint, the visible laser and the infrared laser are emitted in parallel, the position of the invisible laser can be predicted through the visible laser, and the alignment efficiency of the infrared laser is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of wireless optical communication. Background technique [0002] Wireless laser communication technology, also known as free space optical communication technology, is a communication technology that uses light waves as the carrier of information to transmit data under the condition of atmospheric space as the propagation medium.
