Systems and methods for modeling wavefronts in polychromatic light using delay elements.

摘要

A system (20; 20 ') of active remodeling wavefronts, said system device (30; 30 comprising') optical phase shifting arranged to act on light (24) input having at least two wavelengths lambda 1 and lambda 2, forming said input light at least one beam (24), each beam a plurality of sub-beams (26a to 26d; 26th '' to 26b '') contiguous, establishing said subbeams a wavefront (28 ) lambda1 and a wavefront (28) lambda2 respectively, said device offset at least one array (42a-42c, 42 '') of elements, can adjust each element independently to selectively alter the path length optical a respective sub-beam to effect a first remodeled wavefront of said light wavelength lambda1 and a second remodeled wavefront of said light wavelength lambda2, wherein said device mismatch is configured to position light d and wave length lambda1 remodeled and light wavelength lambda2 remodeled over a path (34; 34 '') common beam, characterized in that said first wavefront reshaping is different from said second wavefront reshaping.
