Abstract

Il dispositivo comprende una sorgente generatrice di radiazione luminosa ed è atto ad emettere un flusso luminoso avente caratteristiche prefissate in uno spazio esterno al dispositivo stesso; tale dispositivo comprende inoltre primi mezzi diffrattivi (3) disposti in modo da essere colpiti dalla radiazione luminosa (4) emessa dalla sorgente suddetta ed atti ad emettere un primo flusso di raggi diffratti (5) e secondi mezzi diffrattivi (6) disposti in modo da essere colpiti da detto primo flusso (5) ed atti ad emettere un secondo flusso di raggi diffratti (7); i secondi mezzi diffrattivi (6) sono predisposti per correggere e modificare le caratteristiche dei raggi del primo flusso luminoso (5) in modo che le caratteristiche del secondo flusso luminoso (7) corrispondano alle suddette caratteristiche prefissate.
