Signal laser interferes in fiber coupler, then shapedsignal pulse transmits from output port of this pulse shaper. Signal pulse's waveform is determined by the profile of the nonlinear phase shift.
The synchronous signal of MC1311 CMOS camera is shaped by monostable trigger 74ls221. The data are stored in AT24C02, protected in the case of electricity loss.
Monitoring the signal is very complex, often contain many mutations shaped peak or non-stationary components, the traditional Fourier transform of this signal de-noising can not.
