The object receives modulated light waves from a plurality of light sources, which are arranged in the structure. The modulation is individually coded, and the position of the light sources in the structure is known. The modulation signals are synchronized, and thereby it is possible to determine the position of the object on basis of measuring the phase difference between the phase of each received modulated light wave and a comparison phase. The phase difference is used for distance calculations, which in turn give the position of the object. | 08-19-2010 |
