  In this paper, we propose a new method to characterize the temporal structure
of arbitrary optical laser pulses with low pulse energies. This approach is
based on strong field photoelectron holography with the glory rescattering
effect as the underlying mechanism in the near-forward direction. Utilizing the
subfemtosecond glory rescattering process as a fast temporal gate to sample the
unknown light pulse, the time-dependent vectorial electric field can be
retrieved from the streaking photoelectron momentum spectra. Our method avoids
the challenging task of generation or manipulation of attosecond pulses and
signifies important progress in arbitrary optical waveform characterization.
