Abstract
A depth value of an object is measured. The object is illuminated with a luminaire comprising at least three or more pixel-layers including a first pixel-layer, a second pixel-layer and a third pixel-layer, each pixel-layer including a rectangular array of pixels. One or more images are captured of the object illuminated by the pixel-layers of the luminaire. The depth value of a point on the surface of the object is determined based on the one or more captured images. The spaced-apart pixel-layers of the luminaire are grouped into at least a front group and a back group, and the front group is separated from the back group by a distance that is relatively large as compared to a distance by which the spaced-apart pixel-layers within any one group are separated.
