摘要:
A stand-alone station such as a kiosk (10) includes automated equipment for performing eye examination procedures on a user positioned in the station (11). Information derived from the examination determines possible existence of a correctable medical condition. The station includes a user interface (22) and a fulfillment remedy section (30) that addresses the medical condition, as by fabrication of eyeglasses (32) for correction of refraction error, or by communicating treatments through the user interface to the user for treating such conditions as age-related macula degeneration, Alzheimer's disease, or visual field impairment. The station also includes a payment device (24) allowing the user to directly pay for the procedure and to indirectly pay using identified health insurance coverage.
摘要:
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.
摘要:
A method of measuring the thickness or the rate of change of thickness of a layer as the layer is being formed on a substrate, includes illuminating the layer through the substrate with low coherence light that transmits through the layer; collecting a portion of the reflected light from each optical interface of the substrate and layer with a low coherence interferometer; and, calculating the thickness or the rate of change of thickness of the layer according to the obtained interferometric data.
摘要:
A low temperature method for producing a substantially flat large area image sensor assembly, the method includes the steps of providing a die attach substrate having a substantially planar surface; providing a lead frame having a bonding surface and a plurality of leads extending there from; adhering an imager die to the substantially planar surface of the die attach substrate with a low curing temperature first adhesive; and adhering the die attach substrate with adhered imager die to a bonding surface of the lead frame with a low curing temperature second adhesive for producing an image sensor assembly.
