Abstract
A scanning method for optical scanning of a body includes illuminating the body by a lighting unit and a light receiver unit receives light transmitted from the lighting unit to the body and reflected by the body so that a scanning zone of a scanning unit is defined by the lighting unit and the light receiver unit. Two scanning units each having a scanning region are used, which overlap at least in part in an overlap zone, and at least when the surface of the body is in an overlap zone, the scanning sensitivity of at least one of the scanning units is reduced at least for the overlap zone. At least one scanning unit is used which is configured and/or arranged such that it can scan a part of the body which is as large as possible. A scanning apparatus is also provided for carrying out the scanning method.
