A dynamic model based on the momentum distribution of the final state in the striped photoelectron energy spectra is constructed. An equal-value line reconstruction (ELR) algorithm is proposed, which includes the real momentum-time distribution of the electron wave-packet corresponding to the radiation pulse and is essentially different from the traditional attosecond streak measurement method of FROG-CRAB with a central momentum approximation. The research results show that, compared with those obtained by the FROG-CRAB method, the parameters of the pulse width and the chirp obtained by the method of ELR have a higher accuracy. © 2018, Chinese Lasers Press.
