Abstract
A reflector for projecting a laser beam in a fan-shaped plane of light are provided. Associated with each reflector is at least one light source. Each light source is oriented relative to its associated reflector such that the axis of the beam of light hits the reflector off-center to generate a plane of light that is dispersed less than 360 degrees. Multiple planes of light generated by the reflector and light sources are projected in a common plane such that the independently generated planes of light overlap to create a single plane of light dispersed up to 360 degrees.
