The invention relates to a device for measuring the profile of single optical pulses, comprising:
means (1, F) for creating a series of replica pulses (Ri) of the initial optical pulse, starting from the initial optical pulse (I),
slaving means (2, 3, 4, AMP) for adjusting the amplitudes of replica pulses (Ri) to values substantially the same as each other,
sampling means (7, Ech) for forming optical samples (Ei) starting from replica pulses (Ri), and
detection means (D) for forming an electrical signal starting from the optical samples (Ei).
The invention is applicable to measurement of single optical or electrical pulses or pulses with a low repetition rate.
