It is based on optical sampling that creates a replica of the fast signal on a much slower time scale by a simple strobe effect. High bandwidth detection and acquisition is totally suppressed leading to a better response and a substantial cost reduction. The performance is illustrated by comparative measurements using a Brillouin high resolution distributed fibre sensor.text::conference output::conference proceedings::conference paper
