Light-Based Mechanism For Optical Indicator Guides

An optical guide, comprising:

• a first light source;
• a first surface configured to split a first light beam from the first light source to produce a first plurality of light beams along a first axis,
• wherein the first surface has a first side and a second side opposite to the first side, and
• wherein the first light beam enters the first side and the first plurality of parallel light beams exit the second side;
• a second surface configured to split at least one of the first plurality of light beams to produce a second plurality of light beams along a second axis,
• wherein the second axis changes as the second surface rotates, and is angled from the first axis;
• and
• an adjustment mechanism that adjusts an angle of the second axis relative to the first axis along the rotation axis.
