Abstract
Systems and methods of optical transverse patterning of image-forming light rays include a programming element to generate a pattern that a modulating element imprints onto the image-forming light rays. In some embodiments, the programming element and the modulating element are the same component within the system. In some embodiments, the pattern is free of farfield diffractive artifacts.
Claims30
An optical system, comprising:
- a light source emitting light forming an image;
- a secondary source to generate a pattern;
- a programming element to be modified by the pattern;
- and
- a modulation element disposed along a path of the light and coupled to the programming element to (i) receive the light and (ii) modify a transversely varying optical property of the light in accordance with the pattern, the transversely varying optical property free from farfield diffractive artifacts.
