2.5.1.2 Range Offset Calibration

Unlike the Range Offset parameter, which affects the binned range value, the following pixel offset from the table shown in
Figure 37 does the same for each single pixel range by performing a calibration on a reference plane. The distance in meters
to the reference plane can be entered in the Calibration Target Distance [m] field. After clicking the Run Range Offset
Calibration Sequence button, the table is populated with the values and distance offsets that are written to the sensor. The
generated calibration data can also be imported and exported for further processing or analysis. Single offset values can
also be modified and requested by using the Get and Set buttons.
The main purpose of this calibration procedure is to enable and improve gesture detection applications by minimizing the
range offset among the single pixels of the 32-pixel array on the receiving side. The effect of this calibration is depicted in
Figure 38.
