Publication number: 20250035846Abstract: Introduced here is an approach to mitigating (e.g., lessening or eliminating) the high-frequency interference pattern that is caused by uneven surfaces along the coupling interface formed between the waveguide and probe of an interferometric sensing system. The approach is to reduce the high-frequency interference pattern caused by the interference when a waveguide?for example, in the form of an optical fiber?and a probe are directly coupled to one another. Specifically, the coupling surface of the waveguide can be treated, for example, with sandpaper, sandblasting, or acid etching, to create a frosted surface texture. In operation, the frosted surface scatters the light transmitted through the waveguide, preventing the high-frequency interference pattern from occurring.Type: ApplicationFiled: October 16, 2024Publication date: January 30, 2025Inventors: Hong Tan, Jianbo Yao, Genqian Li, Erhua Cao
