Abstract
We combine the differential confocal microscopy and annular pupil filter together. The theory of differential confocal microscopy and the property of the annular pupil filter are discussed in detail. The results of computer simulation and experiment prove that this method can extend the axial dynamic range and improve transversal resolution of 3D profilometry at sacrificing axial resolution.
