Abstract		An optical system for 3-D chest wall measuring during breathing is described. 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 tested by an adult volunteer, who was breathing in two regimes: rib-cage-dominant and abdomen-dominant. The results show the breathing pattern in a graphical and numerical way.
