  • Patent number: 11347039
    Abstract: Methods and apparatus for optical imaging and scanning of holes machined, drilled or otherwise formed in a substrate made of composite or metallic material. The method utilizes an optical instrument for imaging and scanning a hole in combination with an image processor configured (e.g., programmed) to post-process the image data to generate one complete planarized image without conical optical distortion. The optical instrument includes an optical microscope with confocal illumination and a conical mirror axially positioned to produce a full 360-degree sub-image with conical distortion. In the post-processing step, a mathematical transformation in the form of computer-executable code is used to transform the raw conical sub-images to planar sub-images. The planarized sub-images may be stitched together to form a complete planarized image of the hole.

    Abstract: A light-combining optical imager includes a spatially-curved waveguide-body complemented with at least two and preferably at least three holographic layers disposed on the surface(s) of the waveguide-body to couple light into the waveguide-body, optionally redirect its propagation inside the waveguide-body, and outcouple light from the waveguide body to form an optical image with reduced aberrations and—when desired—while expanding the pupil size of the imager upon propagation of light through the waveguide-body to achieve a one-to-one optical conjugation between an object and an image. At least one of the holographic layers includes potions having different diffraction efficiencies. At least one of the holographic layers is optionally configured to operate as a non-zero optical power lens element.
