Abstract
A method for error correction in a phase-shift measuring system based on an I/Q demodulator for robot positioning applications is proposed. Non ideal effects of the system can make inaccuracy rise unacceptably. These effects are modelled so that the error-correction process reduces the error down to 1–1.5cm, as shown with real measurements, which is highly satisfactory.
