  1. 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。
  2. 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。
  3. 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。
  4. Coherent reference carrier

  5. Then the important reference are provided for the optimal system design and technical parameters selecting of long - range underwater acoustic information transmission system. 2. the underwater acoustic channel model based on ray theory is studied, and in combination with the system function of coherent multi - path channel, the method for underwater acoustic channel response prediction through eigenrays finding is obtained

    研究了基於聲線理論的水聲通道聲場模型，分析並模擬了在多種不同聲速條件下的聲線傳播以及不同海底狀況下的聲傳播；結合相干多途通道的系統函數，通過求取本徵聲線進行了水聲通道響應的預測。
