Abstract
The present disclosure generates an optical spectrogram, representing a temporal change in frequency characteristics, using a plurality of spectral data measured by an OFDR measurement instrument at different times, and filters the optical spectrogram in both a time direction and a frequency direction.
Claims8
An analysis device that generates an optical spectrogram, representing a temporal change in frequency characteristics, using a plurality of spectral data measured by an OFDR measurement instrument at different times, and filters the optical spectrogram in both a time direction and a frequency direction.
A measurement method comprising:
- acquiring a plurality of spectral data by measuring backscattered light with an OFDR measurement instrument at different times;
- generating an optical spectrogram, representing a temporal change in frequency characteristics, using the plurality of spectral data;
- and
- filtering the optical spectrogram in both a time direction and a frequency direction.
