Abstract
A light shaping optic may include a substrate. The light shaping optic may include a structure disposed on the substrate, wherein the structure is configured to receive one or more input beams of light with a uniform intensity field and less than a threshold total intensity, and wherein the structure is configured to shape the one or more input beams of light to form one or more output beams of light with a non-uniform intensity field and less than the threshold total intensity.
Claims20
A light shaping optic, comprising:
- a structure,
- wherein the structure is configured to receive one or more input beams of light with a uniform intensity field and less than a threshold total intensity;
- wherein the structure is configured to shape the one or more input beams of light to form one or more output beams of light with a non-uniform intensity field and less than the threshold total intensity, and
- wherein the threshold total intensity is a threshold at one or more of a particular divergence angle, a particular pulse duration, or a particular exposure direction.
1 more element
A system, comprising:
- an optical transmitter to provide a beam directed toward an object, wherein the beam is associated with a constant intensity across a field of view;
- a light shaping optic to concentrate the beam into one or more areas of concentration,
- wherein the one or more areas of concentration of the field of view are associated with a higher concentration of light than one or more other areas of the field of view, and
- wherein a total intensity of the one or more areas of concentration satisfies a threshold at one or more of a particular divergence angle, a particular pulse duration, ora particular exposure direction;
- and
- an optical receiver to receive a reflection of the beam reflected from the object and perform a plurality of time-of-flight measurements on the beam.
3 more elements
An optical element, comprising:
- a substrate;
- and
- a light shaping optic to provide a non-uniform patterned intensity beam,
- wherein the non-uniform patterned intensity beam includes a set of first areas with a first intensity and a set of second areas with a second intensity,
- wherein the second intensity is between 10% and 90% of the first intensity, and
- wherein a total intensity of the non-uniform patterned intensity beam is less than a threshold at one or more of a particular divergence angle, a particular pulse duration, ora particular exposure direction.
