Abstract
Based on spectral interferometry and Fourier transformation, the method that spectral phase shifts of chirped pulse are transformed to transient temporal phase shifts is investigated theoretically. The error transferring formula of phase shifts from Fourier-domain to time-domain is derived, and the temporal resolution of temporal phase shifts restricted by the spectral bandwidth of reference pulse is given. The transformation process of phase shifts is simulated. The results show that phase shifts obtained is characteristic of temporal change, and the spectral phase shifts error is transferred to time-domain with reduced magnitude, and it is in agreement with calculated result by the error transferring formula.
