Function test and calibration self - heterodyne curve for direction finder on sea trial
More , this paper discusses some important performance parameters of the coherent self - heterodyne botdr system , such as dynamic ranges , spatial resolution , minimum detectable change
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
Based on this , we bring forward a availability and viable distributed fiber sensing for temperature and strain system that based on spontaneous brillouin scattering , coherent self - heterodyne botdr , and done part experimental study
