Abstract

Un procedimento per l'esposizione di pellicole in fogli non esposte e per la scansione foto-elettrica delle pellicole stesse sviluppate è caratterizzato dalla combinazione degli accorgimenti seguenti: a1) un raggio luminoso localizzato viene deviato sulla pellicola per linee e punti;b1) in fase di esposizione di una pellicola non esposta, viene controllata l'intensità del raggio luminoso; a2) in fase di scansione di una pellicola esposta, il raggio luminoso viene rilevato, successivamente al suo attraversamento della pellicola medesima, da uno strumento di misura appositamente previsto; b2) sia per l'esposizione che anche per la scansione si utilizzano, quantomeno in parte, i medesimi componenti ottici e/o meccanici e/o elettronici. (Figura 1).A procedure for the exposure of films in unexposed sheets and for the photo-electric scanning of the films themselves developed is characterized by the combination of the following measures: a1) a localized light beam is deflected on the film by lines and points; b1) in phase exposure of an unexposed film, the intensity of the light beam is checked; a2) when scanning an exposed film, the light beam is detected, after passing through the film itself, by a specially provided measuring instrument; b2) the same optical and / or mechanical and / or electronic components are used, at least in part, for both exposure and scanning. (Figure 1).
