Abstract
The resolution of many imaging systems is often restricted by the limited spatial resolution of its sensing device rather than by diffraction limits related to the optical system. This spatial resolution of the sensor, when limited by the pixels' dimensions, is coined as "geometrical resolution." Earlier, we suggested a technique for overcoming this limit, thus obtaining "geometrical superresolution." The proposed approach is based on capturing a set of images after attaching special predesigned mask to the detector plane, interlacing the pixels of the captured images, and eventually applying inverse filtering over the interlaced image. Experimental results are presented to demonstrate the ability of the suggested technique.
