Problems solved by technology

[0005] In today's short-to-medium distance communication, the transmitting terminal and the receiving terminal still have difficulties in achieving alignment and acquisition, the link is prone to interruption, and the traditional mechanical steering mechanism causes the terminal to be bulky and the link in the communication scenario with limited load carrying capacity. Technical difficulties such as capture difficulties

Embodiment Construction

[0028] Below, the present invention will be further described in conjunction with the accompanying drawings and specific embodiments.

[0029] In order to illustrate the technical solutions of the embodiments of the present invention more clearly, the accompanying drawings of the embodiments will be briefly introduced below. Obviously, the accompanying drawings in the following description are only some embodiments of the present invention, and those of ordinary skill in the art Generally speaking, other drawings can also be obtained based on these drawings on the premise of not paying creative work.

[0030] The large field of view, light and small laser communication optical transceiver is developed around the two technical points of fast capture and stable tracking, involving the design and analysis of three aspects: capture unit, servo unit and communication unit. A new optical system based on double wedge prisms is used to realize the large field of view deflection and pe...

Abstract

The invention discloses a large-view-field light and small laser communication optical transceiver suitable for a light platform, and belongs to the technical field of laser communication. The optical transceiver is composed of a laser emitting unit, a double-optical-wedge prism scanning and capturing unit and a tracking and communication integrated unit, a conventional mechanical servo rotary table is abandoned by using rotary double optical wedges, and the size, the weight and the power consumption of the system are reduced while large-view-field light beam deflection is achieved. Based on the integrated multiplexing technology of the quadrant detector, a tracking light path and a communication light path are combined into one, and the system installation and adjustment difficulty and the optical axis parallelism detection difficulty are reduced.

Description

technical field [0001] The invention relates to the technical field of laser communication, in particular to a light and small laser communication optical transceiver with a large field of view suitable for a light platform. Background technique [0002] Free space wireless laser communication has the characteristics of wide carrier frequency, fast transmission rate, large transmission capacity, strong anti-interference ability, strong anti-interception ability, and strong confidentiality. It has been widely concerned and applied in military and civilian fields. In recent years Wireless optical communication technology has made major technological breakthroughs in atmospheric transmission, high-precision PAT (Pointing, Acquisition and Tracing), and multi-node communication. With the wide application of laser communication technology in light and small unmanned aerial vehicles, the limited carrying capacity of light and small unmanned aerial vehicle platforms has brought grea...
