Abstract
An apparatus and a method are provided for 3-D imaging and scanning using a 2-D planar VCSELs source configured as a lightfiled optical source. VCSELs are configured in different 2-D spatial arrangements including single VCSEL, or preferably a group, cluster, or array each to be operated effectively as an independent VCSEL array source. A set of microlens and an imaging lens positioned at a pre-determined distance collimates radiation from each VCSEL array source to a set of parallel beams. The parallel beams from different VCSEL array sources generated in a rapid pre-determined timing sequence provide scanning beams to illuminate an object. The radiation reflected from the object is analyzed for arrival time, pulse shape, and intensity to determine a comprehensive set of distance and intensity profile of the object to compute a 3-D image.
