Positioning of Sensor and Test Object

6.4.3.1

General

i
Note the following instructions for optimum positioning of the sensor and test object.
- Observe an optimum distance between the sensor and the surface of the test object, see
- Align the sensor with predominantly diffusely reflecting surfaces almost perpendicular to the surface. To avoid direct
reflection, we recommend that you tilt the sensor by a few degrees.
- In the case of partially glossy surfaces, reflections from the test object can be reduced by inclining the sensor by up to
30° with respect to the surface of the test object.
6.4.3.2

Alignment with Crosshair

You will achieve the best results in the mid of the measuring range (focal range of cameras).
Use the positioning pattern to easily and optimally align the sensor in the mid of the measuring range. Align the
pattern of the projection with the superimposed pattern.
