Theory of Operation
The following sections describe the theory of operation of Gocator sensors.
3D Acquisition
Principle of 3D Acquisition
The Gocator 2300 series sensors are line
profiler sensors, meaning that they capture a
single 3D profile for each camera exposure. The
sensor projects a laser line onto the target. The
sensor's camera views the laser from an angle,
and captures the reflection of the light off the
target. Because of this triangulation angle, the
laser line appears in different positions on the
camera depending on the 3D shape of the
target. Gocator sensors are always pre-
calibrated to deliver 3D data in engineering
units throughout the specified measurement
range.
Target objects are typically moved under the sensor on a transportation mechanism, such as a conveyor
belt. The sensor captures a series of 3D slices, building up the full scan of the object. Sensor speed and
required exposure time to measure the target are typically critical factors in applications with line profiler
sensors.
