Digitalni zaslon kot dvodimenzionalna uklonska mreža

Mavsar, Sandra (author), Mohorič, Aleš (mentor)

Periodični sistemi igrajo pomembno vlogo v znanosti in tehnologiji. V začetku 20. stoletja je bila razvita rentgenska kristalografija, ki je izkoristila uklon svetlobe na periodični zgradbi snovi za določanje njene mikroskopske sestave. Uklon opazimo, ko svetloba posega za oviro ali v odprtino z velikostjo, ki je primerljiva z njeno valovno dolžino. V nalogi sem iz interferenčne slike svetlobe določila strukturo LCD zaslona. Iz nastale interferenčne slike sem določila obliko posameznega slikovnega elementa in razporeditev le teh. Dodatno sem sestavo zaslona preverila s svetlobnim mikroskopom in naredila primerjavo med mikroskopsko sestavo in interferenčno sliko.

Abstract

Periodic systems play an important role in science and technology. In the early 20th century, X-ray crystallography was developed, which took advantage of the diffraction of light on periodic structure of matter to determine its microscopic composition. Here I present the study of interference image of light from a digital screen with a goal to determine its structure. From the interference image, I determined the shape of each pixel and the grid parameters. I additionally checked the structure of the screen with a light microscope and made a comparison between the microscopic structure and the interference image.
