  We demonstrate high repetition rate (up to 88 MHz) single shot recordings of pulses shapes, using a novel opto-electronic strategy. The technique is based on the classical spectral encoding technique, but at a much higher repetition rate than with the state-of-art strategy (which is limited by camera speed). In the present demonstration, the signals are coherent THz pulses emitted at SOLEIL, and the resolution is in the ps range. However the technique is not specific to THz pulses and can be potentially adapted to other wavelengths and situations, provided it is possible to imprint the ultrafast signal on chirped laser pulses (through electro-optic sampling, frequency mixing, transient reflectivity, etc.).
