Fiber Optics Sensing is the technique of using optical fibers to monitor environmental and structural changes. NEC Labs America applies fiber optics sensing in urban infrastructure, energy grids, and subsea systems. By capturing strain, vibration, or temperature data across long distances, fiber optics sensing enables scalable and cost-efficient monitoring solutions critical for modern intelligent infrastructure.
We present a generative AI framework based on a conditional diffusion model for distributed acoustic sensing (DAS) data imputation. The proposed DiffOptics model generates high-quality DAS data of various acoustic events using telecom fiber cables.
