Position measurement signal analysis method, for workpiece of e.g. milling machine, compares measurement signal with reference signal formed by combining information signal with interference signal
A probe produces infrared transmission signals when moved from its rest position. The transmission signals are combined with interference signals to form a reception signal, from which an information signal is obtained. A reference signal is formed by combining the information signal with the interference signal through addition or subtraction. The reception signal is then compared with the reference signal to determine the position of the probe. An independent claim is included for an arrangement for evaluating reception signals.
