| The Pixon method achieve sub-diffraction resolution imaging of a tank in a typical battle scene. This level of resolution requires both good signal-to-noise ratio data and excellent PSF sampling. The PSF sampling in this case was 10 pixels per FWHM (see PSF inset in the image of the blurred data) and the SNR was about 500 per pixel. This capability reveals detail, e.g., the tank's main gun, otherwise undetectable in a more poorly sampled image (compare 2.5 pixel/FWHM reconstruction to 10 pixels/FWHM reconstruction). |
