  • Aberration correction of optical traps
    Publication number: 20080316575
    Abstract: A method and system for correcting aberrations in a beam of light including correcting for effects from an undiffracted portion of an input beam. The method and system includes (1) a component for providing a beam of light; (2) a component for applying a diffraction grating pattern to the beam of light to establish an optical gradient to form an optical trap; (3) component for measuring aberration in the beam of light having the applied diffraction grating pattern; (4) component for calculating a phase-shifting diffraction grating encoding the aberration; and (5) component for projecting the phase-shifting diffraction grating in conjunction with the diffraction grating pattern characteristic of the optical trap.
