Abstract
A structure light module comprises: a VCSEL substrate comprising a VCSEL array comprising a plurality of individual VCSELs; a first spacer disposed on the VCSEL substrate; a wafer level lens comprising a glass substrate and at least a replicated lens on a first surface of the glass substrate disposed on the first spacer; a second spacer disposes on the wafer level lens; a DOE disposed on the second spacer, where a structure light is projected from the DOE on a target surface for 3D imaging.
