摘要： An apparatus (10) for obtaining an image of a tooth (20) includes an image sensor and a white light source (12) providing broadband polychromatic light and an ultraviolet light source providing narrow-band light. A combiner (15) directs broadband polychromatic light and narrow band light along a common illumination path to illuminate the tooth. A polarization beamsplitter (18) directs polarized light from the illumination path along an optical axis (216). An optical coherence tomography (OCT) imaging apparatus (70) splits the low coherence light into a sample path and a reference path and a dichroic element (78) directs the polarized illumination and the sample path low coherence light along the optical axis. An image processor (100) identifies a region of interest according to either a white light image (124), a fluorescent light image (120), or both and the OCT imaging apparatus obtains an OCT image over the region of interest.

摘要： 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.

摘要： A digital projection apparatus has a first light modulation subsystem with a first light source producing linear illumination of a first spectral color and a second light source producing linear illumination of a second spectral color. A first light modulator chip has at least two independently addressable linear arrays of light modulating devices. A first spatial filter blocks reflected light and transmits diffracted light along a first optical path. A second light modulation subsystem has at least a third light source producing linear illumination of a third spectral color. A second light modulator chip has at least one independently addressable linear array of light modulating devices. A second spatial filter blocks reflected light and transmits diffracted light along a second optical path. A color combining element directs modulated light onto a common optical path. Projection optics direct modulated light toward a scanning element for projection toward a display surface.

摘要： 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.
