Looking for Video Camera to measure crack length??????

[Cran]

I need to measure crack length in fatigue test of an Aluminium sample automatically. For example, the camera can take shots (Images) every 4000 cycles (fatigue load cycles), maybe more cycles.

For my test, I need to measure both sides crack length (right side and left side of specimen centre line), shown in Fig1.  So I need to take shots both crack tips at the same time, which means camera must have a large field view and the resolution should measure 0.01mm, to see both crack tips clearly. At the end, I must be able to acquire images from Labview. I can save all the images into my fold from Labview, then I can measure crack lengths in left and right side from every image.

 

Would you please give me any suggestions on the characteristic/specifications of this kind of camera?

 What kind of camera can I use? How much this kind of camera? Where can I order this kind of camera?

Do you have the software that will analyze your images? If not, your camera is not your major cost here. 

But for just cameras, check out edmund optics (edmundoptics.com I think).  They have a camera selector guide that will at least give you an idea of the specs you actually need and the price range to look at.
