Patent ID: 7877017

Claim:
An optical waveform measurement system that measures a waveform of signal light, comprising: a signal light generating unit that changes, when the signal light and sampling light are incident on the signal light generating unit, transmittance depending on the sampling light and generates output signal light prepared by matching a frequency of the signal light and a frequency of the sampling light; a jitter removing unit that converts the output signal light into an electric signal having a frequency less than a predetermined frequency and removes a jitter included in the electric signal; a sampling light adjusting unit that adjusts the sampling light incident on the signal light generating unit, based on the electric signal with the jitter removed by the jitter removing unit; and an optical waveform measuring unit that measures the waveform of the signal light, based on the output signal light generated from the sampling light adjusted by the sampling light adjusting unit and being incident on the signal light generating unit.
