Abstract
A sheet-of-light projection system is projects a substantially uniform sheet of laser light (or other electromagnetic radiation) using a fiber-optic bundle. Incidence optics directs a laser beam to be incident to the fiber-optic bundle at a predetermined angle of incidence, resulting in the projection of a sheet of light. For the exemplary embodiment, the angle of incidence is substantially orthogonal to the fiber-optic bundle, resulting in the projection of a substantially planar sheet of light. Thus, the laser projection technique converts a beam of laser light (or other electromagnetic radiation such as UV, visible, IR or microwave radiation) into a radially extending sheet of light that in the exemplary embodiment is substantially planar. In one application, the laser projection technique can be used in the construction industry to project a uniform substantially planar sheet of light for use as a reference marker.
