Title:
METHOD AND DEVICE FOR DETECTING THE SHAPE OF A THREE-DIMENSIONAL OBJECT
Document Type and Number:
WIPO Patent Application WO2003046472
Kind Code:
A3
Abstract:
The aim of the invention is to provide a method and a device which allow detection of the shape of a three-dimensional object at very short measuring times, especially at substantially shorter measuring times than the methods known so far, thereby allowing inter alia the three-dimensional shape detection of fast moving or quickly changing test objects. According to the invention, the propagation times of the light scattered and/or reflected and/or emitted by the object to the measured are encoded as light intensity modulations and the light intensity or light intensity distribution is measured. The shape of the three-dimensional object is determined on the basis of the measured values for the light intensity distribution.
