Abstract

We propose and discuss three methods for increasing the resolution of an aperture limited optical system by illuminating the input with structured light. The kind of illumination can be varied, ranging from tilted plane waves, coherence shaped light or speckle patterns. In any case the high resolution of the projected pattern demodulates the high frequencies of the sample and permits its passage through the system aperture. A decoding process provides the superresolved image after some digital post processing stage.
