摘要: A method and system for correcting aberrations in a beam of light including effects from an undiffracted portion input beam. The includes (1) component providing light; (2) applying diffraction grating pattern to the establish optical gradient form trap; (3) measuring aberration having applied pattern; (4) calculating phase-shifting encoding aberration; (5) projecting conjunction with characteristic trap. also diffractive diffracted portion, apart at least one operating on both bring focus out focal plane; (the trap) modify relative into plane.
