Abstract

Time magnification and heterodyning are combined to allow single-shot characterization of the electric field of optical waveforms. The electric field of the source under test is obtained by Fourier processing of the magnified temporal intensity of the source heterodyned with a monochromatic source. An experimental implementation of this technique is characterized and used to measure various optical signals.
