Is seems that vsion can detect a flow of particals,
Can any one tell me or it also detect smoke particals? or the flow of smoke?

Hi Cees,
Could you please provide much more detail about this? What do you mean by flow of particles? And what do you mean by detect flow of smoke? Do you have any sort of physical specs for this? What I woudl recommend is to try it with two images using Vision Development Module. You can download this for free on ni.com: http://joule.ni.com/nidu/cds/view/p/id/2125/lang/en and try it for 30 days. I'd recommend taking a look at the optical flow VI's.
Cheers,

HI Marti C
Well i want to use it as tool in a windtunnel ,when we do flow detection and all kindo f other stuff on the same time on large objects.
Would be nice if we could see that flow on computer with its path , when we see the flow of the smoke and its direction we can then determine the force.

Isn't a wind tunnel application more of a steady state than dynamic? You aren't trying to measure motion of the smoke particles, are you? It sounds more like you just want to locate the stream of smoke after it has settled into a steady state.
If you could color your smoke a special color, it would be very easy to detect with a color camera or a filter on a grayscale camera. You can do it with white smoke, but then you need a different color background (black preferred) to make the color stand out.

Well we want to see a human with iteracting with its sports device
You aren't trying to measure motion of the smoke particles, are you? yes we want to do that check the motion of the particals like http://en.wikipedia.org/wiki/Particle_image_velocimetry
