Abstract
In a spatially resolving range-finding system, an object is illuminated in a pixelwise fashion by illuminating beams emanating from an array of light sources with returned imaging beams striking a corresponding array of solid state receiving elements. The particular arrangement of the light sources and the receiving elements may be varied. The laser light sources and receiving elements may be selectively operated such that one light source may illuminate one or more receiving elements or several light sources may illuminate a single receiving element. The light sources are driven serially, allowing limits of laser protection regulations to be reliably complied with. An advantage is a substantially better signal quality at the receiving elements.
