摘要
A new method is presented, based on an interferometric spatial autocorrelation of two shifted focal field distributions and the use of a small (fluorescing) bead, to measure the amplitude and phase distribution of the focal field of a high-numerical-aperture (high-NA) lens. The technique can be applied to the measurement of the complex focal field for both CW and ultrashort pulse radiation.
