Abstract: Film contact scanners are provided which irradiate a first surface of a film with a light source, and receive an image of the film from a second side of the film at an array of photosensors. In a first embodiment, the array of photosensors is disposed adjacent the film so that each photosensor receives light from a separate point on the film. In a second embodiment, a bundle of optical fibers is disposed between the film and the array of photosensors. A gap is provided between the film and a first end of the bundle of optical fibers. Each photosensor receives the light from one or more of optical fibers for producing a predetermined MTF. In the second embodiment, a portion of the film between the light source and the bundle of optical fibers is formed in a cylindrical shape. A linear direction of the cylindrical shape is oriented to permit the photosensors to scan the film in a first direction. The film is moved past the bundle of optical fibers in the direction of the curve of the film for scanning the film in a second orthogonal direction. The light source includes either a diffuse illuminator or a specular illuminator. Alternatively, the film is sandwiched between a plate of transparent material, disposed adjacent a first side of the film closest to the source of light, and an area fiber optic for maintaining the film in a substantially flat orientation.

Abstract: A method for mapping a sensor pixel array to an illumination pixel array according to a surface forms a group map by assigning each pixel on the sensor array to a corresponding group of an ordered set of groups, each group defined by a set of p adjacent pixels on the illumination pixel array by projecting and recording at least n projected images from a first set of n binary patterns, with transitions between pixels in each of the n binary patterns only at group boundaries. At least m images from a second set of m binary patterns are projected and recorded, with one or more transitions between pixels in each of the m binary pattern offset from group boundaries. At least p multiline images are projected and recorded. Lines in the recorded multiline images are correlated with lines in the multiline images according to the group map.

Abstract: A method for mapping a sensor pixel array to an illumination pixel array according to a surface forms a group mapping by assigning each pixel to a corresponding group, each group with p adjacent pixels on the illumination array and each ordered set having k groups, by projecting and recording a sequence of group index images. Each group index image has, in at least two of the groups, no illuminated pixels and in fewer than (k−1) groups, from 2 to (p−1) adjacent illuminated pixels. The sequence of group index images uses pixels from each of the k groups. At least p multiline images are projected and recorded, wherein each multiline image projects a line within each group. Lines in the multiline images are correlated according to the group mapping and the correlation stored in memory. Integers k and p are greater than or equal to 3.

Abstract: A method and apparatus for obtaining a color mapping of a dental object. Illumination is directed toward the object over at least first, second, and third wavelength band, one band at a time. An image of the dental object is captured at each wavelength band to form a set of images of the dental object. For pixels in the captured set of images, an image data value for the pixel corresponds to each of the wavelength bands and calculates interpolated image data values proportional to the spectral reflectance of the dental object, according to the obtained image data values and according to image data values obtained from a reference object at the wavelength bands. Spectral distribution data for a viewing illuminant is obtained and the visual color of the dental object reconstructed according to the calculated interpolated image data values and the obtained spectral distribution of the viewing illuminant.
