광섬유 레이저 센서
Abstract
We propose and demanstrate a fiber laser as a sensor, whose output is the frequency of beat signals between eigenpolarization modes of the fiber laser. For the measurement of lateral stress, proportional constant of 4.8 kHz/gram is obtained with a good linearity. For the measurements of temperature and longitudinal strain applied to the polarization maintaining fiber laser, proportional constants of 30 kHz/
