System Integration Questions
I'm looking for a vision system solution in conjuction with Liquid Penetrant Inspection (LPI) also known as Fluorescent dye Penetrant Inspection. The system concept is to visually inspect parts that have been prepared and subjected to UV lighting. The system is to accept or reject conforming and non-conforming parts by identifying cracks. The penetrant dye remains in the cracks and "glows" under UV light.

Serge - detecting the dye "glowing" under UV light is fairly straight forward. i suspect that the challenge in your application will be efficiently presenting the parts to the camera for inspection. Factors such as the physical size of the parts, part geometry (shape) and batch size, among others, would need to be understood before an inspection solution could be specified. If you would like to give me a call at my office, I would be happy to discuss the details with you.
Serge, The only question I have is do you have an old failed part, and some dye, and the dye characteristics. We could run a sample at our machine vision lab, and show you the kinds of results you are going to see. Please feel free to call or email, and we'll see if we can help you.
