Abstract

L'impianto sfrutta le caratteristiche di comportamento della luce laser in presenza di nebbia, e prevede l'impiego di sorgenti laser (41, 43) per luce coerente ed una distribuzione a fibre ottiche da ciascuna di dette sorgenti ad una pluralità di punti luce (41V; 43V, 43B) di segnalazione con emissione di fasci di luce orientati e di divergenza pilotata.
