Georgia State University's Center for High Angular Resolution Astronomy (CHARA), a six-telescope interferometer, excels at ...

Optical fiber interferometer vibration sensors demonstrate a distinctive capability to monitor mechanical vibrations across numerous independent points using a multicore fiber cable, making them ...

The schematic diagram of the φ -OTDR system based on hybrid 3 × 3 coupler and Sagnac interferometer is depicted in Figure 1. The system employs a narrow linewidth laser (NLL) as the light source, ...

An ultra-sensitive optical fiber humidity sensor based on an extrinsic Fabry-Perot interferometer is proposed and experimentally demonstrated in this paper. The Fabry-Perot cavity is constructed by a ...
