Abstract
An optical apparatus includes a substrate that is configured to redirect a predetermined percentage of an input light beam at a plurality of angles to form a set of output beams at each of the angles such that light beams redirected at each of the angles cooperate to form bands of light at a range of predetermined distances from the optical apparatus.
Claims20
An optical apparatus comprising:
- a substrate that is configured to redirect a predetermined percentage of an input light beam at a plurality of angles to form a set of output beams at each of the angles such that light beams redirected at each of the angles cooperate to form bands of light at a range of predetermined distances from the optical apparatus.
An apparatus for splitting a light beam comprising:
- a substrate configured to receive an input beam from a light source and defining a repeating prismatic pattern that includes non-angled facets configured to allow undeviated continuation of a predetermined percentage of the light beam and one or more angled facets configured to generate angularly deviated beams such that the angularly deviated beams sharing a common deviation angle combine to form a band of light at a distance within a predetermined distance range from the substrate.
An apparatus for splitting a light beam comprising:
- a substrate including a microstructure defining a plurality of subpatterns that include non-angled surfaces configured to pass the light beam undeviated, first angled surfaces configured to redirect the light beam at a positive angle, and second angled surfaces configured to redirect the light beam at a negative angle, wherein the microstructure forms sets of light beams that cooperate to form bands of light, corresponding to the non-angled surfaces, the first angled surfaces, and the second angled surfaces, at a range of predetermined distances from the apparatus.
