Geometric superresolution of a CCD pixel
Ihtsham ul Haq, Asloob Ahmad Mudassar · Optics Letters · 2010
In digital imaging, resolution is mostly limited by the nonzero pixel size of the CCD detector. The pixel averages out all the spatial variations falling over it and reduces the overall resolution of the digital image. This Letter introduces a geometric superresolution technique for resolving a pixel into N number of subpixels in one dimension by scanning a mask over it while keeping the imager and scene relatively fixed.
