Line scan cameras
"Mode 1"
In this mode, there is no setup in
"TriggerControls"
necessary (
"TriggerMode"
=
"Off"
).
Now, please follow these steps to run Mode 1 with mvHYPERION:
1. In
"Digital I/O"
set the mode to
"SinglePulse"
of the used CameraLink signal (normally
"DigitalOutputs -
>
CC1"
), which is used for triggering and
(a) define
"Priority"
,
"Delay_us"
and
"Width_us"
(pulse width).
(b) Afterwards, set the
"PulseStartConfiguration"
to
"PulseStartConfiguration0"
.
2. In
"PulseStartConfiguration"
(a) set the
PulseStartTrigger
to
"Periodically"
.
(b) The Property
"Frequency_Hz"
defines the line frequency, which is passed to the camera over
"CC1"
.
"Mode 2"
"TriggerControls"
settings in this mode are optionally.
Following settings in
"Digital I/O"
are necessary:
1. Now, set the wanted mode of the used CameraLink signal (normally
"DigitalOutputs -
>
CC1"
), which is used
for triggering
"TriggerSource"
input (normally
"Trigger-In"
):
(a)
"SinglePulse"
: On the basis of
"PulseStartConfiguration"
a signal is created and given to the camera for
triggering. Delay time and pulse width can be defined.
(b)
"PassThrough"
: The signal of the chosen input will be negated in timing and pulse width or not passed
to the camera. Please choose
"Sync-In"
as input. No further settings are necessary.
2. In
"PulseStartConfiguration"
set the
PulseStartTrigger
to
"DigitalSignal"
:
(a) Set
"DigitalSignal"
to the wished input (normally:
"Sync-In"
).
(b) If the signal happens too fast, you can divide the trigger frequency with the
"TriggerDivider"
.
(c)
"TriggerMoment"
shows the starting time with falling or rising edge.
Now, after a external trigger signal on the sync input of the frame grabber, a trigger signal is generated on the
CameraLink connection (
"CC1"
) and passed to the camera. In order to that, the camera acquires an image and
sends it to the frame grabber. It is possible to trigger the image acquisition of the frame grabber externally. For this,
please do following:
1. In
"Image Settings -
>
Camera -
>
TriggerControls -
>
Frame Start"
set
"TriggerMode"
to
"On"
.
2. Choose the
"TriggerSource"
input (normally
"Trigger-In"
).
3. Choose the
"TriggerActivation"
according to the application (e.g.
"FallingEdge"
,
"RisingEdge"
, etc.).
Per image and frame trigger, the number of lines will be acquired, which were defined in the camera description and
the AOI setting before.
