Design of Laser Communication Optical Transceiver Based on Double Wedge Prisms
With the popularization of laser communication to the platforms with limited load capacity, laser communication system is developing towards lightweight and miniaturization. As a key role of laser communication, the design of scanning and acquisition unit is also need to be lightweight and miniaturized. In this paper, first, the double wedge prisms based scanning and acquisition unit abandons the conventional mechanical servo structure, which realizes beam deflection in large field of view by independently rotating the prisms around the common rotation axis. Then, the beam deflection model and the scanning pattern model of double wedge prisms are established by using non-paraxial ray tracing method, and the scanning mode of the double wedge prisms is analyzed, which provides a certain reference for the development of light and miniaturized laser communication optical transceivers. Finally, the design and application of a kind of light-weighted and miniaturized laser communication optical terminal is proposed and analyzed based on rotating double wedge prisms and quadrant detector multiplexing technology.
