Abstract

Proces poznat kao računalno generirana holografja (RGH) podrazumijeva da se hologram generira numerički. S obzirom na matematički opis valne fronte objekta predstavljenog skupom točaka, moguće je izračunati interferentnu strukturu holograma i prikazati rezultat na zaslonu računala ili ispis na odgovarajuću podlogu. Ispis podrazumijeva prijenos interferentne strukture na transparentnu foliju pomoću grafčke tehnike ispisa. Stoga se pojam „računalno generirana holografja“ sve više koristi da označi cijeli procesni lanac sintetičke pripreme holografskih svjetlosnih polja pogodnih za promatranje. U radu se koristila uobičajena metoda CtF (Computer to Film) tehnologije za generiranje pristupačnih otisaka visoke rezolucije koji se mogu prvenstveno koristiti u poslovnom te zaštitnom tisku. Cilj ovog rada je pomoću programa Adobe Photoshop kreirati različite zaštitne dizajnerske uzorke sačinjene od segmenata računalno generiranih holograma sa svrhom zaštite i očuvanja informacija. U procesu izrade potrebno je pripaziti na određene parametre i svojstva kako bi postigli kvalitetnu pripremu za ispis. S obzirom na to da nam svojstvo redundancije omogućuje dizajnerske intervencije na samom hologramu, ispitani su parametri očuvanja tog svojstva prilikom njihove aplikacije.

Abstract (english)

The process known as computer-generated holography (CGH) involves the hologram being generated numerically. Given the mathematical description of the wavefront of an object represented by a set of points, it is possible to calculate the interference structure of the hologram and display the result on a computer screen or print it on a suitable substrate. Printing involves the transfer of an interfering structure to a transparent foil using a graphic printing technique. Therefore, the term “computer-generated holography” is increasingly used to denote the entire process chain of synthetic preparation of holographic light felds suitable for observation. This study has used the method of CtF (Computer to Film) technology to generate affordable high-resolution prints that can be used primarily in business and security printing. The aim of this paper is to use the program Adobe Photoshop to create various protective design patterns composed of segments of computer-generated holograms for the purpose of protecting and preserving information. In the process, it is necessary to pay attention to certain parameters and properties in order to achieve quality preparation for printing. Since the redundancy property allows us to make design interventions on the hologram itself, the parameters of preserving this property during their application were examined.
