You have been beaten to it by about 50 years. I have used some of their products (National Instruments) 20 years ago. But they may not cover visual inspection images for data acquisition, I have seen some specialized systems to inspect welds with Xrays. These are probably the biggest guys in US. http://www.ni.com/ I haven't looked through their site recently, guess the switched to dotNet DWUTKA at marlow.com wrote: >Okay, this isn't a technical question, it's more like a marketing one.
