Latest Patents

One of his latest patents is a spectral filter system for infrared imaging of substrates through coatings. This invention provides an improved system for visual inspection of substrates coated with paints and polymers. It allows for the inspection of painted substrates for environmental and physical damage, such as corrosion and cracks, without the need to remove the paint. The system maximizes paint thickness penetration using a spectral bandpass filter that rejects reflected light from the coating's opaque bands while allowing light in the paint window to pass to an IR detector. This innovation enhances the ability of infrared imaging to see through thicker paint layers and improves contrast over standard commercial IR mid-wave cameras.

Another significant patent is a computer-controlled optical system for angular alignment of structures. This system utilizes an optical imaging input to a computer to synthesize regularly spaced reference and test line patterns. These patterns are combined to create an interference pattern, where the spacing of moire fringes indicates the necessary movement of structures for predetermined alignment. The process is observable on the interference display, providing a quantitative measure of angular alignment. An operator-programmed template automatically processes moire edge alignment measurements, streamlining the alignment process.
