Analiza pegavosti pri laserskem osvetljevanju kavitacijskih pojavov : zaključna naloga Univerzitetnega študijskega programa I. stopnje Strojništvo - Razvojno raziskovalni programOgrinc, Luka, inženir strojništvaHitro spreminjajoče se pojave, kot so udarni valovi pri lasersko povzročeni kavitaciji, je težje opazovati, zato potrebujemo posebne napredne osvetlitvene sisteme, ki so sposobni ustvariti kratke ... laserske pulze trajanja nekaj nanosekund. Zaradi teh pa pogosto pride do pegastega vzorca na sliki, kar je posledica interference svetlobe, s katero osvetljujemo. V okviru naloge smo naredili digitalno analizo slik in določili kontrast pegavosti, ki je posledica stopnje koherence osvetlitve. Ugotovili smo, da na izračun kontrasta vpliva ozadje in opravili tudi zaznavo udarnega vala s pomočjo bilateralnega filtriranja.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [L.
