the minimum pulse width which can be detected by HRTC has to be at least 5 us.
1.18.10.3 Creating double acquisitions (HRTC)
Note
Please have a look at the Hardware Real-Time Controller (HRTC) (p. 70) chapter for basic information.
If you need a double acquisition, i.e. take two images in a very short time interval, you can achieve this by using the
HRTC.
With the following HRTC code, you will
• take an image using TriggerSet and after TriggerReset you have to
• set the camera to ExposeSet immediately.
• Now, you have to wait until the first image was read-out and then
• set the second TriggerSet.
The ExposureTime was set to 200 us.
