Subpixel processing of digital images obtained with CCD matrix

The methods of signal analysis of photosensitive array and related conventional methods of digital filtering of time series is essentially the same as those in other areas of science and technology. Subpixel processing are peculiar, perhaps, only the inverse filtering procedure, providing high resolution of single reflections with limited pixel size photosensitive matrix. Combination of two matrix counts shifted by half a pixel, followed by deconvolution, resolution can increase in two times.
