Design of a new optical system to generate narrowband guided waves with an application for evaluating the health status of rail material
he Letter presents a new design of Sagnac interferometer based optical system (SIOS) that emits a line-arrayed pattern generating narrowband high-energy waves in a specimen. The SIOS is further used to excite Rayleigh waves in a pristine rail specimen to evaluate its intrinsic nonlin earity resultin...
