Abstract
A light section is generated on the object with an arrangement for the contactless section-like form measurement of curved surfaces by means of an optical detector functioning in a raster-like manner. The light section is received at an angle inclined to the viewing axis by an anamorphotic system and imaged onto a receiver.
