Measurement across reflectivity or <strong>co</strong>lour transitions<br />
Fig. 20<br />
To minimize spot centre of gravity shifts, orient the sensor triangulation plane in<br />
parallel with the transition !<br />
Sensor alignment<br />
Fig. 21<br />
The sensor tilt in the triangulation plane may be optimised for best repeatability after<br />
sensor exchange, surface structure insensitivity etc. by <strong>co</strong>ntrol of a known step height<br />
difference and a fine pitched tilt adjustment.<br />
Use precision, mirror polished, gauge blocks as target.<br />
OK !<br />
