Classification: CPC G  H | IPC G  H

Claim 13:
14. The ultrafast camera system of claim 11, wherein the timing detector comprises
a loop interferometer that modulates the optical signal using the reference signal in a loop where the optical signal is divided and the divided signals circulate in different directions, and outputs two interference signals generated from interference between the signals circulating the loop,
a first spectrum analyzer that receives a first interference signal in the two interference signals, disperses the first interference signal into the wavelength spectrum, and measures an intensity of dispersed continuous wavelength signals,
a second spectrum analyzer that receives a second interference signal in the two interference signals, disperses the second interference signal into the wavelength spectrum, and measures an intensity of the dispersed continuous wavelength signals, and
a computing device that outputs an intensity difference between two measurement signals measured by the first spectrum analyzer and the second spectrum analyzer.
