Abstract

A better signal-to-noise ratio is obtained during measurements with the disclosed process by selecting an optimized base (A') composed of n scanning functions (S1, S2, ..., Sn). After the scanning measurement values (f*) are projected by calculating the scalar product from the measurement values and scanning functions (f*.S1T, f*.S2T, ..., f*.SnT), an inverse transformation is finally carried out in order to obtain a unit base (A) representation from the optimized base (A') representation.
