摘要：An apparatus (5) for measuring the dimensions of an object (1) where ameasuring carriage (6) moves the object at a distance thereabove. A polygonal mirrorunit (32) receives laser light (16) and reflects it in a fan-shaped form toward a stationaryangled mirror unit (37, 38) which directs the light towards a double-curved stationarymirror unit (39) which reflects the beam onto the object. Mirrors (40) of the polygonalunit are adjustable.
