<p>Apparatus for determining the three-dimensional shape of an object by projecting, onto the object's surface, fringe patterns characterized by a sinusoidal spatial variation of light intensity, said apparatus comprising means (30, 34, 36) for changing the pattern centred on the optical projection axis (28), and cam means (54) for transversally shifting the patterns (12a, 12b) over distances equivalent to 2π/n phase shifts.</p> |
