ABSTRACT:
Given a situation where a projected laser line appears to have terminated or faded as it intersects with a work-surface (e.g., a wall), a fan-out redirecting means is used to capture and redirect energy radiating above and parallel to, or radiating away from the given work-surface area, where the captured energy is from a line projector mounted to the surface. The radiation capturing and redirecting means aims the captured energy at a greater angle towards the work-surface so that the redirected light is thereafter reflected back to a user to give the perception that a line of enhanced intensity or reborn existence is being created on the work-surface or on a reflective overlayer placed against the work-surface. The radiation capturing and redirecting means may include one or both of optically refractive means and optically reflective means (e.g., lens and mirrors) for performing the capturing and/or redirecting functions.
