Direct three-dimensional measurement and imaging of oil spills via stimulated Brillouin scattering

Year: 2025

Type: article

Abstract: We developed a scanning stimulated-Brillouin-scattering (SBS) instrument for three-dimensional (3D) measurement and imaging of oil slicks and underwater mixture targets. To do this, we designed and experimentally demonstrated a setup that integrates a scanning system with an interferometer system comprising a Fabry-Perot etalon and an ICCD camera. Our experimental results indicate that the SBS system can accurately measure the frequency shifts of various media and clearly identify the boundaries of oil slicks and submerged oil through point-by-point scanning. Our results demonstrate that the instrument system can map the underwater 3D topography through point-by-point scanning of the Brillouin spectrum and can successfully identify the cross-media targets. This work is essential to future applications of SBS in marine environment monitoring and may be extended to characterize the mechanical properties of material.
