9.2.7 Sensor Tilting
Tilt angles of the sensor in diffuse reflection both around the X and the Y axes of less than 5 ° only have a
disturbing effect with surfaces which are highly reflecting. Tilt angles between 5 ° and 15 ° lead to an apparent
distance change of approximately 0.12 ... 0.2 % of the measuring range, see Fig. 47.
Tilt angles between 15 ° and 30 ° lead to an apparent distance change of approximately 0.5 % of the measu-
ring range. These influences must be considered especially when scanning structured surfaces. In principle
the angle behavior in triangulation also depends on the reflectivity of the target.
