Classification: CPC G | IPC G

Claim 0:
1. A method of processing an optical signal, the method comprising:
calibrating an optical system, the calibration comprising:
acquiring, by one or more processors, at least a first mirror measurement and a second mirror measurement, the first and second mirror measurement being collected from either side of a zero-delay line;
obtaining, by the one or more processors, an amplitude and phase for the first mirror measurement and the second mirror measurement;
resampling, at least one of the first mirror measurement and the second mirror measurement to be at least one of: (i) in linear wavenumber (k) space or (ii) linear wavelength or (iii) linear time, to generate a resampled mirror measurement;
performing spectral flattening on at least one mirror measurement by using an envelope calculated from a specific mirror measurement; and
calculating, using a function, an optimized fit for the resampled mirror measurement.
