ABSTRACT:
A single fiber laser light projection system consists of 3 primary elements: (1) a secured fiber capable of generating specular reflections of laser light; (2) a laser beam whose beam diameter exceeds the cross-sectional diameter of said fiber; and (3) an intersection between the fiber and the laser beam at any angle through 90 degrees. Any angle of intersection less than 90 degrees will generate a cone of laser light. The directional tangent of the fiber at the point of intersection will define the cone's vortex, while the laser light will be distributed along the cone's perimeter. When the angle of intersection between the laser beam and the fiber is 90 degrees, a plane of laser light will be projected. A plurality of reflective fibers can be secured to a support structure for use with an incident laser beam. These multiple fibers can be arranged in an orderly fashion for aesthetic purposes, and to support ornamental items such as crystals. A laser beam can be directed into this multiple fiber projection system under the direction of an electromechanical mirrored scanner. Single and multiple fiber laser light projection systems can be used to resolve industrial, educational, military, and aesthetic laser scanning matters in an efficient, economical, and reliable manner.
