Trigger Selector#
Once selected, you can use the trigger type for a number of camera configuration tasks, e.g., enabling hardware triggering.
Using the Feature#
Selecting a Trigger Type#
To select a trigger type, set the TriggerSelector parameter to one of the following values (if available):
- FrameStart
- FrameEnd
- FrameActive
- FrameBurstStart
- FrameBurstEnd
- FrameBurstActive
- ExposureStart
- ExposureEnd
- ExposureActive
Common Tasks#
Once you have selected a trigger type, you can do the following:
Task | Feature |
---|---|
Enabling or disabling the selected trigger type | Trigger Mode |
Selecting the input line or software command to act as the source for the trigger type selected | Trigger Source |
Selecting the signal transition necessary for activating the trigger type selected | Trigger Activation |
Configuring a delay between the receipt of a hardware signal and the moment when the trigger type selected becomes effective | Trigger Delay |
Available Trigger Types#
Frame Burst Start (= Acquisition Start), End, and Active Trigger#
Info
The Frame Burst Start trigger and the Acquisition Start trigger are identical, only the names differ. The naming depends on your camera model. In the following, the term "Frame Burst Start trigger" is used to describe both types.
If available, you can use the Frame Burst Start, End, and Active triggers to control the acquisition of a series of images (a "burst" of images).
The number of images per series is specified by the AcquisitionBurstFrameCount parameter. The maximum number of images per series depends on your camera model.
By default, these triggers are disabled, and the camera acquires single images only.
If you enable these triggers and the camera receives the corresponding signal via the trigger source configured, the following happens:
- Frame Burst Start: The camera initializes the acquisition of a series of images.
If the Frame Start trigger is enabled, the camera is now ready to receive Frame Start trigger signals.
If the Frame Start trigger is disabled and the Exposure Start trigger is enabled, the camera automatically initializes the next image.
If the Frame Start trigger is disabled and the Exposure Start trigger is also disabled or not available, the camera automatically acquires the entire series of images. - Frame Burst End: The camera finalizes the acquisition of a series of images.
If this trigger is disabled or not available, the camera automatically finalizes the series after the last image acquisition. - Frame Burst Active: When the trigger signal rises, the camera generates a Frame Burst Start trigger signal. When the trigger signal falls, the camera generates a Frame Burst End trigger signal. You can change this behavior using the Trigger Activation feature.
Frame Start, End, and Active Trigger#
Info
- If you want to use any of these triggers, the exposure mode must be set to Timed or TriggerWidth.
- If the exposure mode is set to TriggerControlled, these triggers can't be enabled, i.e., their TriggerMode setting will permanently be set to Off.
If available, you can use the Frame Start, End, and Active triggers to control the acquisition of a single image. These are the trigger types used most commonly. In most image applications, you will only need to configure these trigger types.
By default, these triggers are disabled, and the camera controls image acquisition automatically.
If you enable these triggers and the camera receives the corresponding signal via the trigger source configured, the following happens:
- Frame Start: The camera initializes the acquisition of one image.
If the Exposure Start trigger is enabled, the camera is now ready to receive Exposure Start trigger signals.
If the Exposure Start trigger is not available or disabled, the camera automatically starts exposing the image. Note that in this case, exposure starts with a delay (see exposure start delay). - Frame End: The camera finalizes the acquisition of one image.
If this trigger is disabled or not available, the camera automatically finalizes image acquisition after exposure. - Frame Active: When the trigger signal rises, the camera generates a Frame Start trigger signal. When the trigger signal falls, the camera generates a Frame End trigger signal. You can change this behavior using the Trigger Activation feature.
Exposure Start, End, and Active Trigger#
If available, you can use the Exposure Start, End, and Active triggers to control the exposure of a single image.
Info
- If you want to use any of these triggers, the exposure mode must be set to TriggerControlled.
- If the exposure mode is set to Timed or TriggerWidth, these triggers can't be enabled, i.e., their TriggerMode setting will permanently be set to Off.
- If you want to use the Exposure Start and End triggers, you must enable both for them to work.
By default, these triggers are disabled, and the camera exposes images automatically.
If you enable these triggers, set the exposure mode to TriggerControlled, and the camera receives the corresponding signal via the trigger source configured, the following happens:
- Exposure Start: The camera starts exposing one image.
- Exposure End: The camera stops exposing one image.
- Exposure Active: When the trigger signal rises, the camera generates an Exposure Start trigger signal. When the trigger signal falls, the camera generates an Exposure End trigger signal. You can change this behavior using the Trigger Activation feature.
Using the Trigger Types#
Use Case 1: Frame Burst Triggering#
Assume you want to trigger the acquisition of a series of images with only one trigger signal.
To achieve this, enable the Frame Burst Start trigger and disable all other available trigger types. Also, set the AcquisitionBurstFrameCount parameter to 3.
This way, every time the camera successfully receives a Frame Burst Start trigger signal, the camera automatically acquires a complete series of three images.
Afterwards, the camera waits for the next Frame Burst Start trigger signal. On the next trigger signal, the camera acquires another 3 images, and so on.
Use Case 2: Exposure Triggering#
Assume that you want to avoid the exposure start delay, i.e., start exposure as fast as possible after applying a trigger signal. Also assume that the Exposure Start trigger is available for your camera.
In this case, set the exposure mode to TriggerControlled, enable the Frame Start trigger and the Exposure Start trigger, and disable all other available trigger types.
This way, every time the camera successfully receives a Frame Start trigger signal, the camera initializes image acquisition, but does not yet start exposing. Instead, the camera waits in its prepared state and is ready to expose immediately when receiving an Exposure Start trigger signal.
After the image has been exposed, the camera ignores all further Exposure Start trigger signals. You must apply a new Frame Start trigger signal to initialize the next image acquisition.
