A Method of Permanently Controlling the Thickness and Profile of a Processed Photographic Emulsion

Pages 190-192 | Received 14 Jul 1975, Published online: 22 Jul 2016
 

Abstract

It has becn found that the thickness and profile of a processed photographic emulsion layer can be permanently altered by imbibing a watcr-solublc monomer into the laycr and polymerizing it in situ. This has particular application in controlling the reconstruction of holographic images.

Résumé

Il est possible de fixer l’épaisseur et le profil d’une couche d’émulsion photographique après traitemenl en l’imprégnant avec un monomère soluble dans l’eau et en provoquant la polymérisation in situ. Cette technique est employee en particulier pour maitrïser la reconstruction d’image holographiques.

Zusammenfassung

Es wurde gefunden, daß Dicke bzw. Profil einer verarbeiteten Emulsionsschicht durch Einbringen eines wasserlöslichen Monomeres und anschließende Polymerisation in situ definiert eingestellt werden kann. Die Methode wird insbesondere zur Erzielung einer optimalen Rekonstruktion holographischer Bilder verwendet

Riassunto

Si è trovato che è possibile alterare in modo permanente lo spessore e il profilo di uno strato sviluppato di una emulsione fotografica imbibendo lo strato stesso con un monomero idrosolubile e polimerizzandolo “in situ”. Questa tecnica trova una particolare applicazione nel controllare la ricostiluzione di immagini olografiche.
