Abstract:
1. A laser scanner comprising a transmission optic ( 20 ) whose laser pencil beam ( 18 ) is oriented coaxially with an axis of rotation ( 28 ) of a rotating deflecting mirror ( 22 , 24 ) and coaxially with an optical axis of an associated detector optic ( 58 ) such that the light reflected by a distant measuring point ( 44 ) can be deflected by said deflecting mirror ( 22 , 24 ) and through said detector optic ( 58 ) to a signal detector ( 68 ) whose output signal ( 70 ) can be evaluated for purposes of data acquisition, characterized in that said transmission optic ( 20 ) is disposed in a shading cylinder ( 62 ) that is open to said deflecting mirror ( 24 ) and that extends from the region of said detector optic ( 58 ) coaxially with the axis of rotation ( 28 ) of said deflecting mirror ( 22 , 24 ) into the vicinity of said deflecting mirror ( 22 , 24 ).
