Abstract
At least one two-dimensional infrared grid is projected onto a three-dimensional subject in order to determine or represent contours of the subject based on distortion of the grid. The grid is separated from a composite visible-infrared image by a beam splitter. If two grids are superposed for a stereoscopic effect, the two grids preferably have different infrared wavelengths and are separable by a second beam splitter.
