The system is based on a laser multiple-line triangulation technique. It uses a CCD camera and a laser that simultaneously projects thirty-three light planes on the measured surface. The accuracy is 0.5 mm, the measuring range is 400x600x500 mm and the frequency is 80 Hz. The system efficiency was testedby an adult volunteer, who was breathing in two regimes: rib-cage-dominant and abdomen-dominant. The results show the breathing patternin a graphical and numerical wayTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Ljubljani, Fakulteta za strojništvo
