1. A sheet-of-radiation projection system that projects a substantially uniform sheet of electromagnetic radiation;

  • comprising;

    (a) a source of a beam of electromagnetic radiation;

    (b) a bundle of substantially parallel dielectric waveguides; and

    (c) incidence optics, optically coupled to the beam source, that directs the beam to be incident to the bundle of dielectric waveguides at a predetermined angle of incidence;

    (d) such that a sheet of radiation is projected from the bundle of dielectric waveguides.
