Active Area
Active area refers to a region of interest within the sensor’s maximum field of view that defines the area
used for laser profiling.
By default, the active area covers the sensor’s
entire field of view. If your application requires
the entire field of view, then there is no need
to configure the active area. By reducing the
active area, the sensor may be able to operate
at higher speeds.
Active area is specified in sensor coordinates,
rather than system coordinates. Refer to the To
clear recorded data: (page 39) in this chapter
for more information on sensor and system
coordinates.
Active Area can only be set when the sensor is
in none calibrated state (reference to calibration
state section) and using None layout (or a single
sensor system).

To set the active area:
1 Navigate to the Sensor Panel.
Active area is specified separately for each sensor.

Laser profiling devices are usually more accurate at the near end of the measurement range. If your application
requires a measurement range that is small relative to the maximum measurement range of the sensor, mount
the sensor such that the active area can be specified at the near end of the measurement range.
