2-D planar VCSEL source for 3-D imaging

摘要

An apparatus (710) and a method are provided for 3-D proximity sensing, imaging and scanning using a 2-D planar VCSEL array source (730) using reflected radiation from an object (720) being detected. An important feature of the apparatus (710) is a compact high power optical source and in particular, an optical source (730) comprising a plurality of VCSELs to illuminate the object (720). VCSELs in the optical source are configured in different 2-D planar arrangements, such that the optical source may be used in many different modes to adapt to different sensing, imaging and scanning requirement suited for different environments including one where shape, size and illumination mode require to be altered dynamically. When used in different modes of operation the apparatus (710) provides a comprehensive set of measured distance and intensity profile of the object (720) to compute a 3-D image.
