AbstractThe development of a two‐dimensional noncontact electrooptical orientation sensor is addressed in this article. The sensor is based on the intensity measurement of modulated light signals reflected from the surface of an object. The transducer of the proposed sensor was designed based on the optimal mechanical‐design parameters obtained in the first stage of our research, where results were reported for one‐dimensional inclination angle measurements. Experiments undertaken in the second stage of our research, and reported herein, verify the operational principle of the two‐dimensional sensor, which yielded acceptable performance characteristics. An important characteristic of this orientation sensor is the distance‐independent inclination‐angle measurements (i.e., output signals utilized to estimate the two inclination angles are independent of the sensor's distance to the object
