brillouin light 中文意思是什麼
brillouin light
解釋
布里淵輻射-
Among those nonlinear effects, stimulated brillouin scattering has the worst effects on the fiber hydrophone system due to its low threshold and it produces a new light wave which is different from the incident light in frequency. this dissertation discusses the physical mechanism and quantum explanation of sbs in fiber
在眾多非線性效應中，由於受激布里淵散射（ stimulatedbrillouinscattering ）效應的閾值最低，且產生了與入射光場不同頻率的新的光場，故對光纖水聽器系統而言，影響最大的即是受激布里淵散射效應。 -
At the same time, it uses a frequency translator to obtain a frequency shift, which is equal to the brillouin frequency in fiber. then the detecting pulsed light and the cw reference light can coherent. this method greatly improved the system ’ s sensitive and signal to noise ratio ( snr )
同時在探測光路中引入一個光移頻環路，使探測光移頻后再經光纖中布里淵頻移，其後向布里淵散射光頻率與參考光束大致相當，可進行相干自外差探測，大大提高了系統的探測靈敏度以及系統的信噪比。 -
