Abstract

The invention provides an underwater laser light source system and an underwater wireless optical communication system, the underwater laser light source system comprises a laser light source, and anaspheric lens and a beam expanding collimating lens group which are sequentially located on an emergent light path of the laser light source, and the laser light source is located at the focus of theaspheric lens; the laser source is used for emitting laser; the aspheric lens is used for collimating the laser along the fast axis direction and the slow axis direction so as to compress the divergence angle of the laser into a first preset range; the beam expanding collimating lens group comprises a plano-concave lens and a plano-convex lens which are sequentially located on an emergent light path of the laser light source, and the beam expanding collimating lens set is used for carrying out beam expanding collimation on the laser, so that the divergence angle of the laser emitted by the underwater laser light source system is small, and it can be guaranteed that the transmission distance of the laser in water is long enough and the power density is large enough.

Description

technical field [0001] The invention relates to the technical field of wireless optical communication, and more specifically, relates to an underwater laser light source system and an underwater wireless optical communication system. Background technique [0002] The underwater environment is rich in natural resources, however, 95% of the underwater environment is currently undeveloped. like figure 1 As shown, the underwater unmanned submersible vehicle (Autonomous Underwater Vehicle, AUV) 10 and the underwater sensor network (Underwater Sensor Network, UWSN) 20 are the key devices for the development of the underwater environment, however, a long distance is required between these devices , High-bandwidth wireless communication for data transmission. [0003] Among the existing wireless communication methods, compared with electromagnetic wave communication and acoustic wave communication, optical communication is more suitable for underwater environment development due t...
