In optical field analysis, like restoration of optical phase from phase-modulated images, data acquisition is the primary step in practical reconstruction algorithm. The relation between the experimental sampling rate and the sampling rate request by a particular algorithm is very important. A prior knowledge of the field characteristics cannot be ever done. In this paper we present a self-consistence criterion, based on Wittaker-Shannon theorem, for fields reconstruction algorithms. The criterion correlate the energy of the output database using primary data acquisition with the energy of a database obtained by sub-sampling initial data and can increase the confidence in the result of a reconstruction algorithm applied to a specific input field. We apply the criterion to validate the phase restoration of a following- pass, inverse cosine transform algorithm.
