1. A distortion measuring device comprising:

  • a Brillouin scattered light spectrum recorder that records a spectrum of Brillouin scattered light generated in a device under test as a result of supplying incident light;

    an incident light spectrum recorder that records a spectrum of the incident light;

    a Brillouin gain spectrum deriver that derives a Brillouin gain spectrum of the device under test based on the recorded spectrum of the Brillouin scattered light and the recorded spectrum of the incident light;

    a peak frequency deriver that derives a peak frequency at which the derived Brillouin gain spectrum takes the maximum value; and

    a distortion deriver that derives a distortion of the device under test based on the derived peak frequency.
