Abstract
A light source comprises an array of Vertical Cavity Surface Emitting Lasers (VCSELs) and an optical member. The array comprises at least two sub-arrays. The sub-arrays are displaced with respect to one another along a first axis. The optical member is configured as a single optical element and configured to transform light emitted by the sub-arrays into substantially parallel illumination lines in a target area. The illumination lines are arranged along the first axis. Each illumination line has a width in a direction of the first axis and a length in a direction of a second axis perpendicular to the first axis. The width is smaller than the length. The optical member has facets in the direction of the second axis. Each facet has a size in the direction of the second axis which is smaller than a size of a sub-array in the direction of the second axis.
