Latest Patents

One of Yun Fu's latest patents is a "Distributed acoustic sensing system based on space-division multiplexing with multi-core fiber." This innovative system maintains the advantages of single-ended measurement found in standard distributed acoustic sensing (DAS) systems. It enhances the strain resolution by accumulating the intensity of Rayleigh backscattering light within each core of the multi-core fiber. The introduction of an optical switch allows different code sequences to transmit simultaneously across the various cores, enabling single-pulse responses with coding gain without sacrificing frequency response bandwidth. Additionally, the use of space-division multiplexing allows multiple pulses with precise time delays to be transmitted simultaneously, significantly improving the frequency response bandwidth of the DAS system.

Another notable patent is the "Long-distance fiber optic distributed acoustic sensing amplification system and method thereof." This system includes a distributed amplification unit that utilizes a LEAF, a pump, and a WDM to achieve distributed amplification. The method involves modulating and amplifying a light source to create probe pulse light, guiding both pump and probe light into the LEAF, and combining them for distributed amplification. This process generates power-raised Rayleigh backscattered light, which is then converted and demodulated to complete the distributed sensing.
