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.
