Dewesoft cameras

For applications requiring video which is truly synchronized to the dynamic sample rate, there is support for DS cameras. A high-
quality image with the automatic shutter speed (selectable) is controlled directly by the A/D card, which generates a pulse to drive
the camera. The result is a stunning correlation between each frame and the data.

Thermo cameras are supported by Optris, and Ultra-High-Speed cameras from Photron can acquire more than 2 million frames per
second but in limited resolution.

[Video available in the online version]
