ABSTRACT:
An automated system for illuminating and inspecting the inner surface areas of tubular samples, especially stents, is disclosed. The system comprises rotatable means for receiving the sample to be inspected; at least one fluorescent surface area arranged in the immediate vicinity of the sample to be inspected; an UV-light source for illuminating the at least one fluorescent surface area; an electronic line-scan camera for inspecting the sample; and a computer based electronic imaging system, functionally connected to the camera, whereby the imaging system creates a line-by-line image of an area extending along the length of the sample as it rotates under the camera.
