Abstract
In this paper, we present a novel position measurement method that makes use of a couple of plane light sources created from an IR-LED matrix array and a photo-detector. The light sources emit light with the same frequency, but different phases, while the optical axes of the sources are set up orthogonally. Then, the signal place is diffused by the space with phase differences in each position. Finally, the signal received by the photo-detector is analyzed to determine the position.
