Abstract
A method of manipulating a focused light beam includes focusing a beam of excitation light with a lens to a focal spot within a sample, where a cross-section of the beam includes individual beamlets. Directions and/or relative phases of the individual beamlets of the excitation beam at a rear pupil of the lens are individually varied with a wavefront modulating element, and emission light emitted from the focal spot is detected while the directions or relative phases of individual beamlets are varied. The directions of individual beamlets are controlled to either maximize or minimize the emission light from the focal spot, and the relative phases of individual beamlets are controlled to increase the emission light from the focal spot.
