Gocator Line Profile Sensors: User Manual
Gocator Web Interface • 105
Mode and Option Description
Uniform Spacing
When this option is enabled, ranges are resampled to a uniform spacing along the X axis
(Spacing (Data Resampling) on page 59 for more information). The size of the spacing can be set
in the Spacing tab (see Spacing Interval on page 122).
When the option is disabled, the Gocator outputs unprocessed range data. Ranges are reported
in (x,z) coordinate pairs. Post-profiling processing is disabled. Only a subset of the measurement
tools is available.
Disable this option to extract ranges from the Gocator at the highest possible rate.
When the sensor is in Surface mode, this option is not available.
The Y offset, X angle, and Z angle transformations cannot be non-zero when
Uniform Spacing is unchecked. Therefore, when aligning a sensor using a
bar alignment target with Uniform Spacing unchecked, set the Degrees of
Freedom setting to X, Z, Y Angle, which prevents these transformations
from being non-zero.
If you are using a layout in which sensors are angled around the Y axis in
order to capture "side" data, you must uncheck Uniform Spacing.
However, currently, only a limited set of built-in measurement tools are
able to perform measurements on the resulting data. If more complex
measurements are required, data can be processed using an SDK-based
application instead.
Acquire Intensity When this option is enabled, an intensity value will be produced for each data point.
Triggers
A trigger is an event that causes a Gocator sensor to take a single image. Triggers are configured in the
Trigger panel on the Scan page.
When a trigger is processed, the laser is strobed and the camera exposes to produce an image. The
resulting image is processed inside the sensor to yield a profile (range/distance information), which can
then be used for measurement.
The sensor can be triggered by one of the sources described in the table below.
If the sensor is connected to a Master 400 or higher, encoder and digital (external) input signals
over the IOcordset are ignored. The sensor instead receives these signals from the Master; for
encoder and digital input pinouts on Masters, see the section corresponding to your Master in
Master Network Controllers on page 625.
If the sensor is connected to a Master 100 (or no Master is used), the sensor receives signals
over the IOcordset. For information on connecting encoder and digital input signals to a sensor
in these cases, see Encoder Input on page 622Digital Input on page 621Encoder Input on page
