Abstract
A ribbon-of-light projection system projects a substantially uniform ribbon of laser light (or other electromagnetic radiation) using a fiber-optic bundle, plano-mirrors, and a plano-cylindrical lens. 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. The sheet of light is then projected towards the cylindrical lens where it is collimated into a ribbon. For the exemplary embodiment, the angle of incidence is orthogonal to the fiber-optic bundle. Thus, the laser projection system converts a beam of laser light (or other electromagnetic radiation such as UV, visible, IR or microwave radiation) into a collimated ribbon of light that in the exemplary embodiment is substantially uniform. In one application, the laser projection technique can be used in industrial applications to monitor the flow of fluids.
