6.2. Trigger Mode
The term trigger means a signal generated by an event that provokes another event.
In our instance, the trigger is a signal generated by a device that triggers image acquisition.
When the sensor is used to inspect moving objects, it is important to ensure that the object is inside
the detection area at the precise instant the image is captured for processing. To this purpose, there
are 3 "trigger" options available in the System menu:
• Continuous
• Hardware - Rising edge
• Hardware - Falling edge
Continuous trigger
The acquisition of the image to be processed is performed at the fastest speed possible. Each
individual image is acquired and immediately processed; as soon as the sensor is ready, the next
image is acquired and so on.
This type of trigger is useful to test the settings of an inspection tool: In fact, it is possible to check the
settings applied to the images acquired by the sensor.
