6.4.2 Calibration
The calibration of the sensor is performed using the entire matrix and is independent from the selected mea-
suring field.
The trapezoidal shape of the measuring field results from the projection onto the sensor matrix. The standard
measuring range is framed in the center.
A sensor acceptance report is enclosed for each sensor. Three diagrams for the linearity measurement which
are briefly explained in the report are included in the sensor acceptance report. The key diagram in the sen-
sor acceptance report is shown again below
, see Fig. 25 .

Fig. 25 Linearity deviation, example of an scanCONTROL 29xx-50
The black points show the places where the measurement error exceeds the linearity limit of 0.08 mm (de-
pending on sensor model). The measurement error increases at both ends of the depth range and particu-
larly in the remote corners. These areas should therefore be avoided for the measurement.
