Optical data communication system using light diffusing fibers
The granted patent US12055764B2 describes a communications system featuring a unique configuration of an outer and inner ring, which are oriented in the same plane and separated by a gap that forms a loop. This system includes a modulating light arrangement that generates modulated light in response to incoming data. Two light diffusing optical fibers are positioned on one side of the gap, extending in different directions to create an optical data ring around the inner ring. These fibers receive portions of the modulated light and diffuse it along the loop, while a detector on the opposite side of the gap captures the diffused light to facilitate data communication between the two sides.
The patent further details the functionality of the system, including the rotatability of the inner ring relative to the outer ring and the specific configurations of the light diffusing optical fibers. It also describes additional components such as modulators, light sources (like LEDs or lasers), and detectors, which work together to ensure effective data transmission. Notably, the system can be integrated into various applications, including medical devices and military vehicles, where it can serve as part of a rotor and stator mechanism for turret rotation. The design also incorporates features to prevent cross-talk between different data channels, enhancing the reliability of the communication system.
