1. An apparatus, comprising:
- two or more scan modules, each scan module having two or more laser sources that generate two or more laser beams characterized by different wavelengths and a beam deflector that deflects the two or more laser beams;
a fluorescent emissive sheet (FES) that receives the two or more laser beams deflected by the beam deflectors of the two or more scan modules and emits light of longer wavelength than that of the two or more laser beams at portions of the FES that are struck by the two or more laser beams, wherein the two or more scan modules are disposed on a same side of the FES; and
imaging optics that form a virtual image from the light emitted from the portions of the FES that are struck by the two or more laser beams.

Abstract
An apparatus includes a scan module having one or more laser sources that generate one or more laser beams and a beam deflector that deflects the one or more laser beams; a fluorescent emissive sheet (FES) that receives the one or more laser beams deflected by the beam deflector and emits light at portions of the FES that are struck by the one or more laser beams; and imaging optics that form a virtual image from light emitted from the portions of the FES that are struck by the one or more laser beams, wherein the FES is between the scan module and the imaging optics.
