Benefits of technology

This technology allows for faster connection between different devices over longer distances by utilizing laser beams that are sent through an air gap or other medium instead of being precisely aligned with each device's position.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving wireless opaqueness while maintaining secure communications over longer distances due to environmental effects or device constraints caused by glare from sunlight during outdoor activities.

Embodiment Construction

[0014] The wireless optical communication system based on cloud scattering of the present invention includes a light sending device and a light receiving device. The light sending device is composed of a plurality of light source arrays that have been optically calibrated. The receiving aperture of the detector, the system establishes a non-line-of-sight link of wireless optical communication based on cloud scattering, and establishes a non-line-of-sight communication link at two remote points to achieve fast and efficient scattered light communication.

[0015] The light sending device includes a light source 1, a driving module 2, and an optical sending lens 3. The driving module 2 drives the light source 1 to emit light to the cloud through the optical sending lens 3. The light-receiving device includes a photodetector 4, a signal processing module 5, an optical receiving lens 6 and an aperture 7. The optical receiving lens 6 receives the light transmitted to the cloud throu...

Abstract

The invention discloses a wireless optical communication system based on cloud scattering. The system comprises a light transmitting device and a light receiving device, wherein the light transmitting device is composed of a plurality of optically calibrated light source arrays; the light receiving device takes a large-aperture receiving lens as a receiving antenna, and the receiving aperture of a detector is changed by an aperture slot; a non sight distance link for the wireless optical communication is created based on the cloud scattering; and non sight distance communication links are created at two long-distance points, so that quick and high-efficiency scattering light communication is realized. In the system, a light signal is emitted by the light emitting end, and the scattered light signal is detected at the receiving end after the light signal is scattered by the cloud in the sky, so that real-time communication is realized. According to the wireless optical communication system disclosed by the invention, the requirements on the alignment accuracy on an optical antenna in the wireless optical communication system are lowered and the non sight distance communication links can be quickly created at the two long-distance points, so that the high-efficiency scattering light communication is realized.
