Patent ID: 7579582

Claim:
A scanning method for an optical scanning of at least a part surface of a body ( 10 , 60 ), comprising: providing at least two scanning units ( 26 , 30 , 36 , 46 , 50 ), each including a lighting unit and a light receiver unit, each of the scanning units having one scanning zone ( 28 , 32 , 38 , 48 , 52 ) defined by the lighting unit and the light receiver unit, wherein the scanning zones of at least two scanning units overlap at least partly in an overlap zone ( 40 ); illuminating the body with the lighting units of at least two of the scanning units; receiving light transmitted from the lighting units onto the body and reflected by the body using light receiver units of the at least two scanning units; and reducing the scanning sensitivity of at least one of the scanning units 26 , 30 , 36 , 46 , 50 ) for the overlap zone ( 40 ), when the surface of the body ( 10 ) is in the overlap zone, in which the scanning zones of the at least two scanning units ( 26 , 30 , 36 , 46 , 50 ) overlap.
