Optical Superresolution through the Combination of Confocal Scanning Microscopy and Apodization

The application of an appropriate apodization film to an ordinary lens makes the point amplitude response asymptotic to a Dirac-delta function, or causes an arbitrarily narrow depth of focus. This implicates that we may achieve lateral or axial superresolution through implementing an apodization film. However, the large sidelobes spreading all through the field, which are produced by imposing an apodization film onto an ordinary lens, may result in a noisy background degrading the image contrast. In this paper, we put forward a scheme of implementing a confocal setup to suppress the large sidelobes. Furthermore, a configuration for achieving three-dimensional suoerresolution is depicted and discussed.
