ABSTRACT:
A cone-of-light projection system projects a shell 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 conical shell of light. For the exemplary embodiment, the angle of incidence is non-orthogonal to the fiber-optic bundle, resulting in the projection of a conical shell 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 conically extending shell of light that in the exemplary embodiment is substantially conical. In one application, the laser projection technique can be used in industrial applications to assist in joining a cylindrical element to another surface.
