Physical Principles of Settings for Apparatus Functions in the measuring systems

Physical Principles of Setting (PPS) of Apparatus Functions (AF) of measuring systems (PPS AF) on the sizes of domains of determination AF are proposed. Sizes of AF O definition region are chosen so that its inverse resolving function R = O-1 in the chosen discrete domain has a minimal norm. In the PPS AF method, the result is reversible; there is no "a priori smoothness of solutions" with a residual error, as in the regularization method. Action of PPS method is demonstrated on the example of the Sun radio image super-resolution in comparison with a result obtained by regularization one.
