This effect – usually a change in polarization, which is turned into a change in optical power at a polarizer – can then be measured without requiring a very fast photodetector.Ī full waveform of a periodic signal can then be obtained by slowly varying the arrival time of the probe pulse, i.e., by sequential sampling of a repetitive signal.įor each setting of the relative time delay, the signal obtained can be averaged over many pulses, so that noise is averaged out and a very high sensitivity is achieved. When ultrashort optical pulses are used in the electro-optic probe, there is only a short time interval in which the electric field at the probe can influence the light.
