Fiber-optic distributed acoustic sensing (DAS) has proven to be a revolutionary technology for the detection of seismic and waves with ultralarge scale ultrahigh sensitivity, is widely used in oil/gas industry intrusion monitoring. Nowadays, single-frequency laser source DAS becomes one bottlenecks limiting its advance. Here, we report dual-comb–based coherently parallel concept, enabling linear superposition signals scaling comb-line number result unprecedented sensitivity enhancement, straightforward fading suppression, high-power Brillouin-free transmission that can extend distance considerably. Leveraging 10-line comb pairs, world-class limit 560 fε/√Hz@1 kHz 5 m spatial resolution achieved. Such combination dual-comb metrology may open an era extremely sensitive at fε/√Hz level, leading creation next-generation geophones sonars.

Optical fibre sensors are an essential subset of optical technology, designed specifically for sensing and measuring several physical parameters. These offer unique advantages over traditional sensors, making them gradually more valuable in a wide range applications. They can detect extremely small variations the parameters they to measure, such as analytes case biosensing. This high sensitivity allows subtle temperature, pressure, strain, refractive index analytes, vibration, other environmental factors with exceptional accuracy. Moreover, these enable remote capabilities. Since light signals used carry information, elements be placed at distant or inaccessible sites still communicate data back central monitoring system without signal degradation. In recent times, different attractive configurations approaches have been proposed enhance fibre-based sensor briefly explained this review. However, we believe that choice configuration should designated based on specific application.
