Domain sensor: a new device to capture complete experimental discrete data

A new measurement device is presented. Extreme design care is devoted to achieve a closer relation between the structure of the mathematical description and the finite-resolution properties of physical detectors that characterize any real measurement process, than previous attempts described in scientific and technical literature. In fact, experimental data are captured by means of a pair of active sensors, placed at a relative fixed distance, working in a coupled arrangement. The presented device operates in a discrete variable domain. Beyond the operational advantages in term of simplicity and computational speed, it agrees with the results of biological observation which reveals that highly structured data always come from coupled transducing bio-elements. A numerical example is presented: an optimal computational precision level can be selected according to the required output precision. Furthermore, it can be showed that for that required precision, the output discrete data set is consistent under inversion transformation.
