Razvoj optičnega merilnika topografije kože : magistrsko delo magistrskega študijskega programa II. stopnjeMrak, Marko, 1989-V magistrskem delu je predstavljen razvoj optičnega merilnika za tridimenzionalno izmero površine kože. Najprej je podan pregled obstoječih metod, v nadaljevanju pa je predstavljena naša rešitev, ki ... temelji na principu optične triangulacije s ploskovnim osvetljevanjem. V ta namen smo zasnovali sklop fotografskega in projekcijskega objektiva, ki ga pritrdimo na ohišje komercialno dostopnega zrcalnorefleksnega digitalnega fotoaparata. Pri tem smo za svetlobni izvor projektorja uporabili vgrajeno bliskavico. Rešitev vključuje tudi Scheimpflugov princip za medsebojno poravnavo polj globinske ostrine. Pred razvojem opto-mehanske konstrukcije je bila izvedena analiza optičnih aberacij s ciljem doseganja ustrezne merilne natančnosti. Merilni sistem je umerjen z referenčnim telesom, pri čemer znaša merilno območje 20 x 15 x 7 mm in prostorska natančnost 0.05 mm. Najkrajši čas za zajem slike je 5 ms. Rezultati testnih meritev na koži in različnih kovinskih vzorcih kažejo, da merilnik izpolnjuje zastavljene cilje glede prostorske natančnosti in enostavnosti uporabe, zato se bo v prihodnje lahko uporabljal za spremljanje oblike površine kože med raznovrstnimi medicinskimi terapijami.Type of material - master's thesis ; adult, seriousPublication and manufacture - Ljubljana : [M.
