Abstract: A method for forming a stereoscopic image forms separate left-eye and right-eye images in a repeated cycle that forms the left-eye image by providing data for lines of the left-eye image, ordered in sequence from a first to a second edge of an image frame, then forms successive lines of modulated light according to the ordered sequence by progressively scanning lines of modulated light across a display surface by rotating a scanning element forward from a first to a second position. The right-eye image is formed by providing data for lines of the right-eye image, ordered in sequence from the second to the first edge of the image frame and forming successive lines of modulated light, progressively scanning the lines of modulated light across the display surface by rotating the scanning element in reverse from the second to the first position. The left-eye image is distinguished from the right-eye image.

Abstract: An apparatus for imaging a tooth having a light source with a first spectral range and a second spectral range. A polarizing beamsplitter (18) light having a first polarization state toward the tooth and directs light from the tooth having a second polarization state along a return path toward a sensor (68), wherein the first and second polarization states are orthogonal. A first lens (22) in the return path directs image-bearing light from the tooth, through the polarizing beamsplitter (18), toward the sensor (68), and obtains image data from the redirected portion of the light having the second polarization state. A long-pass filter ( 15) in the return path attenuates light in the second spectral range. Control logic enables the sensor to obtain either the reflectance image or the fluorescence image.

Abstract: A method for caries detection uses an image capture device (30, 32) to obtain fluorescence image data from the tooth (20) by illuminating the tooth to excite fluorescent emission. A first enhanced image of the tooth is then obtained by illuminating the tooth at a first incident angle, obtaining a back-scattered reflectance image data from the tooth tissue, and combining the back-scattered reflectance image data with the fluorescence image data. A second enhanced image of the tooth is then obtained by illuminating the tooth at a second incident angle, obtaining a back-scattered reflectance image data from the tooth tissue, and combining the back-scattered reflectance image data with the fluorescence image data. The first and second enhanced images are then analyzed to select and display the best-contrast image. This method provides high contrast images for carious regions (58) on all tooth surfaces.
