Gocator Line Profile Sensors: User Manual
Gocator Web Interface • 101
If laser profiling is not satisfactory, adjust the exposure values manually. Switch to Video mode to use video
to help tune the exposure; see Exposure on page 98 for details.
Multiple Exposure
The sensor combines data from multiple exposures to create a single laser profile . Multiple exposures
can be used to increase the ability to detect light and dark materials that are in the field of view
simultaneously.
Up to five exposures can be defined with each set to a different exposure level. For each exposure, the
sensor will perform a complete scan at the current frame rate making the effective frame rate slower.
For example, if two exposures are selected, then the speed will be half of the single exposure frame rate.
The sensor will perform a complete multi-exposure scan for each external input or encoder trigger.
The resulting profile is a composite created by combing data collected with different exposures. The
sensor will choose profile data that is available from the lowest-numbered exposure step. It is
recommended to use a larger exposure for higher-numbered steps.
To enable multiple exposure:
1. Go to the Scan page.
2. Expand the Sensor panel by clicking on the panel header or the button.
3. Click the button corresponding to the sensor you want to configure.
The button is labeled Top, Bottom, Top-Left, or Top-Right, depending on the system.
Exposure is configured separately for each sensor.
4. Click the Exposure tab.
5. Select Multiple from the Exposure Mode drop-down.
6. Click the button to add an exposure step.
