Abstract This paper reviews the recent advances on the high-performance distributed Brillouin optical fiber sensing. which include the conventional distributed Brillouin optical fiber sensing based on backward stimulated Brillouin scattering and two other novel distributed sensing mechanisms based on Brillouin dynamic grating and forward stimulated Brillouin scattering. respectively. ... https://www.allfixelectricales.shop/product-category/gas-shutoff-valve/
