Abstract: A 3D imaging apparatus with enhanced depth of field to obtain electronic images of an object for use in generating a 3D digital model of the object. The apparatus includes a housing having mirrors positioned to receive an image from an object external to the housing and provide the image to an image sensor. The optical path between the object and the image sensor includes an aperture element having apertures for providing the image along multiple optical channels with a lens positioned within each of the optical channels. The apparatus also includes a transparent cover positioned within the optical path and having a plurality of fiducials. The depth of field of the apparatus includes the cover, allowing the fiducials to be used to calibrate the apparatus or verify and correct the existing calibration of it.

Abstract: A 3D image apparatus using a single optical channel for capturing multiple view-angle images of an object for use in generating a 3D image or model of the object. The apparatus includes within the optical train an active optical component, an aperture plate having an aperture, a lens for focusing light from the aperture, and an image sensor. The active optical component has a changeable shape or position for providing first and second optical wavefronts through the aperture and focused by the lens onto the image sensor from first and second view angles of the object. The second optical wavefront is shifted by the active optical component on the image sensor with respect to the first optical wavefront in order to provide multiple view-angle images along the single optical channel, which can be used to generate a 3D model or image of the object.
