In the third part, we give the theoretical deduction and the experiment setup of the two self reference image holograms of the original objects illuminated by coherent light
第三部分給出了相干光照明物體時形成的兩種自參考像全息圖:透射型自參考像全息圖和反射型自參考像全息圖。 -
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。 -
Be different with other botdr systems, the coherent self - heterodyne botdr system uses only one consecutive laser. the light from consecutive laser is divided into two beams, the detecting light and the reference light, by a coupler
與其他的botdr系統分別使用兩臺激光器不同,自相干外差的布里淵散射分散式光纖傳感系統採用一臺激光器,經耦合器分為兩路光束? ?探測光和參考光束。 -
