WebOutils. Les "systèmes de détection acoustique distribuée" (ou DAS pour distributed acoustic sensing) basés sur la diffusion de Rayleigh utilisent des fibres inutilisées de câbles à fibres optiques pour fournir une détection de signaux de contrainte de fréquence acoustique, tout au long de la fibre (d'où le qualificatif de "distribuée" ). WebBy controlling the laser intensity, only a sparsely distributed small number of fluorescent molecules in the imaging area are activated at a time. ... R. J.

WebWe recommend a sensor size of at least 3 times the largest diameter. For the pixel pitch (or, equivalently, pixel size), we recommend that the smallest beam you will measure should fit within at least 10 pixels. For example, if the sensor has a pixel pitch of 5.5 µm, you should not try to measure beams smaller than 55 µm with it.
