Optical fiber temperature automatic calibration and compensation method of optical fiber temperature distribution tester

The invention discloses an optical fiber temperature automatic calibration and compensation method of an optical fiber temperature distribution tester, and relates to the field of optical fiber temperature calibration and compensation. According to the method, Stokes and anti-Stokes automatic calculation is taken as a basis, Stokes and anti-Stokes data in an optical fiber temperature distributiontester are deeply analyzed, and automatic identification of a temperature calibration point and automatic calculation of temperature compensation are realized. Meanwhile, aiming at the condition thatthe actual application length is changed, the invention provides a method for compensating the power of a reflected signal, the function of automatically correcting and calculating parameters is realized, and the automatic test method saves the labor cost, has high calibration precision and high calibration efficiency, does not need hardware modification, and does not increase the hardware cost, and the temperature compens
