The determination of measurement accuracy using information entropy

Abstract

Most technical measuring and technological equipment, instruments and systems, such as having linear and circular scales, measuring transducers or numerically controlled machine tools have information measuring systems (IMS), that provide information on the position of the part of the machine or instrument and other measuring information. The IMS are calibrated against the reference standards of measure comparing their accuracy at some pitch of calibration. It depends on the adopted standards and methodical documentation of these machines or instruments.
