Superresolution in confocal scanning microscopy.
We describe three simple pupil function filters that, in conjunction with a confocal optical system, result in a transfer function that is constant for all spatial frequencies up to the cutoff. We confirm our predictions experimentally by considering a straight-edge object. Edge gradients up to 2.36 times as sharp as the unapodized confocal case are obtained.
