Abstract
The present invention relates to a laser device () for projecting a structured light pattern () onto a scene (). The device is formed of several arrays () of semiconductor lasers (), each array () comprising an irregular distribution of emission areas () of the semiconductor lasers (). One or several imaging optics () image said arrays () to an imaging space and superpose the images of said arrays () in the imaging space to form said light pattern (). The proposed laser device generates a light pattern with high contrast and efficiency which may be used for 3D imaging systems, e. g. in automotive applications.
