Abstract
It is proposed to extract data on the temporal characteristics of an optical signal by spectrally resolving the radiation and recording the nonlinear-optics effect of the resolved radiation. The recording should be made in two planes, with the spectrum image sharp in one of them and out-of-focus in the other. The dependence of the nonlinear effect on the phase relations of the spectral components of the radiation is analyzed. It is shown that if the spectral instrument is suitably chosen it is possible to determine (to within inessential constants) the phases of the spectral components from the frequency dependence of the nonlinear effect.
