Embodiment

[0054] The following is a specific embodiment of the periscope-type laser pointing mechanism with continuous ring scanning function.

[0055] Such as figure 1 As shown, the azimuth axis assembly and the pitch axis assembly are connected through a dual-axis connecting lens barrel; the output lens barrel is connected to the output end of the pitch axis assembly, and a set of elliptical reflectors are respectively installed on the 45-degree slopes of the dual-axis connecting lens barrel and the output lens barrel The mirror provides a turning function for the light path.

[0056] The output lens barrel is pressed on the docking base through a set of shape memory alloy locking and releasing device. After entering the orbit, the unlocker is unlocked and the pointing mechanism can rotate freely.

[0057] Two sets of mirror assemblies are responsible for the deflection of the light path. The periscope-type laser pointing mechanism is a large hollow structure, which serves as the pa...

Abstract

The invention relates to a periscope-type laser pointing mechanism with continuous ring-scanning function. An azimuth axis casing is fixedly connected to a spacecraft, and an azimuth axis main axis is located inside the azimuth axis casing and can be rotated relative to the azimuth axis casing. The shaft connection lens barrel is an L-shaped tubular structure, and the azimuth reflector is installed at the corner, and the azimuth reflector is located on an inclined plane that is 45 degrees from the central axis of the azimuth axis main axis; The dual-axis connection lens barrel is driven to rotate together relative to the azimuth axis housing; the pitch axis assembly includes the elevation axis housing and the elevation axis main axis, the other end of the dual axis connection lens barrel is fixedly connected to the elevation axis housing, and the elevation axis main axis is located on the elevation axis Inside the casing, it can rotate relative to the pitch axis casing, and the main axis of the pitch axis is fixedly connected with the output lens barrel to drive the output lens barrel to rotate relative to the pitch axis casing; there is a conductive space between the azimuth axis casing and the azimuth axis main shaft. Rings for rotational electrical transmission.

Description

technical field [0001] The invention relates to a periscope-type laser pointing mechanism with continuous ring scanning function, which belongs to the technical field of space laser communication. Background technique [0002] Laser communication has the characteristics of fast transmission rate, high bandwidth, and good confidentiality. It is one of the important means of inter-satellite and satellite-to-earth communication in the future. The laser pointing mechanism is one of the three core units of the laser communication terminal (laser pointing mechanism, telescope, and transceiver channel), and is mainly responsible for the initial capture and stable tracking of the laser link. The periscope laser pointing mechanism is a special type of laser pointing mechanism. It is a two-dimensional turntable integrating mechanics, electricity, light, and heat. It has multiple functions such as azimuth scanning, pitch yaw, and optical path turning. . [0003] The traditional peris...
