  • Plural light source and camera to detect surface flaws
    Patent number: 7663745
    Abstract: A method for detecting specular surface flaws on a coated substrate includes impinging visible non-integrated electromagnetic radiation from a first source onto the coated substrate, reflecting the visible non-integrated electromagnetic radiation off the coated substrate into a first photosensitive device, forming a recorded high frequency surface flaw image, and impinging visible coherent electromagnetic radiation from a second source onto a coated substrate at an oblique angle. The visible non-integrated electromagnetic radiation and the visible coherent electromagnetic radiation on the coated substrate are collocated but not combined on the substrate. The visible coherent electromagnetic radiation is reflected off the coated substrate onto a screen material to form a low frequency surface flaw image. The low frequency surface flaw image is recorded to form a recorded low frequency surface flaw image.

  • Specular surface flaw detection
    Patent number: 7362450
    Abstract: An apparatus and a method for detecting low frequency specular surface flaws on coated substrates is disclosed. A method for detecting low frequency specular surface flaws may comprise: impinging visible electromagnetic radiation or light from an electromagnetic radiation source onto the coated substrate at an oblique angle, reflecting the visible electromagnetic radiation off the coated substrate onto a screen material to form a specular surface flaw reflected image, and recording the reflected image off the screen material with a photosensitive device to form a recorded reflected image.

  • Fiber optic specular surface flaw detection
    Publication number: 20070146692
    Abstract: An apparatus and a method for detecting low frequency specular surface flaws on coated substrates is disclosed. A method for detecting low frequency specular surface flaws may comprise: impinging visible electromagnetic radiation or light from an electromagnetic radiation source via a plurality of optical fibers onto the coated substrate, reflecting the visible electromagnetic radiation off the coated substrate as a reflected image, and recording the reflected image with a photosensitive device to form a recorded image.
