Abstract

Dynamic radiation beam shaping methods and systems, comprising: providing a radiation source for delivering an input radiation beam; disposing a first optical element substantially adjacent to the radiation source; disposing a second optical element substantially adjacent to the first optical element; and moving one or more of the first optical element and the second optical element relative to one another such that either an output radiation beam has a variable predetermined shape or the output radiation beam maintains a predetermined shape when the input radiation beam is varied. Optionally, the first optical element and the second optical element each comprise a freeform shape and predetermined diffractive characteristics, refractive characteristics, reflective characteristics, hybrid characteristics, gradient index materials, metamaterials, metasurfaces, subwavelength structures, and/or plasmonics. The one or more of the first optical element and the second optical element are one or more of translated laterally with respect to an optic axis, rotated about the optic axis, tilted with respect to the optic axis, and separated along the optic axis.
