The e method of the invention consists of carrying out: a linear optical filtering of the signal for which it is desired to measure the amplitude of the pulses by means of an acoustic interaction between the optical signal and a colinear or quasi-colinear acoustic beam, mixing in a non-linear response electro-optical element of optical beams diffracted by the acoustic beam, followed by at least one detector for detecting the light intensity derived from the mixer, or at least one integration detection of the square of the optical intensity diffracted by the acoustic beam.
Method for measuring the phase and/or amplitude of ultrashort pulses of a light signal, said method comprising:
Device for measuring the phase and/or amplitude of ultrashort pulses of a light signal said device comprising a component carrying out an acousto-optic interaction between said signal and colinear or quasi-colinear acoustic and optical beams and at least one integrator-detector for detecting the square of the light intensity diffracted by the acoustic beam.
Device for measuring the phase and amplitude of ultrashort light pulses of the light signal, said device comprising a component carrying out an acousto-optic interaction between the light signal and colinear or quasi-colinear acoustic beams, at least one non-linear optical crystal for mixing the optical signals diffracted by the acoustic beam and at least one integrator detector for detecting the light intensity derived from said mixing crystal.
