An apparatus for imaging a tooth has at least one illumination source for providing an incident light having a first spectral range for obtaining a reflectance image of the tooth and a second spectral range for exciting a fluorescence image of the tooth. A first polarizer having a first polarization axis and a compensator in the path of the incident light of the first spectral range are disposed to direct light toward the tooth. A second polarizer is disposed to direct light obtained from the tooth toward a sensor and has a second polarization axis that is orthogonal to the first polarization axis. A lens is positioned in the return path to direct image-bearing light from the tooth toward the sensor for obtaining image data. A filter in the path of the image-bearing light from the tooth is treated to attenuate light in the second spectral range.

Apparatus and method for caries detection

A method of making an OLED device, including providing a substrate having a first electrode and a conductive bus line provided over the substrate and organic EL media provided over the first electrode and over the conductive bus line; forming a radiation absorbing structure associated with the conductive bus line; exposing the radiation absorbing structure to radiation to produce heat sufficient to ablate a portion of the organic EL media thereby forming an opening in the organic EL media; and forming a second electrode over the organic EL media, and through the opening in the organic EL media thereby forming an electrical connection between the second electrode to the conductive bus line.

Electrical connection in OLED devices

A method for dynamically registering multiple patterned layers on a substrate () comprises: depositing a first layer on the substrate; printing a first pattern () on the first layer; depositing a second layer on the first pattern; and printing a second pattern on the second layer while dynamically detecting the first pattern to align the second pattern with the first pattern.

Dynamic compensation system for maskless lithography

Beam scanning system includes a rotatable element for receiving a stationary light beam at successive element facets to thereby impart a scanning motion to the light beam so as to scan a beam receiving medium. Deviation in the mechanical or optical performance related to each successive facet are corrected by use of a high-speed beam deflector operated in either a closed loop or open loop servo system. The beam deflector includes a unique piezoelectric plate and reflecting body structure, wherein parallel plates of piezoelectric material are bonded at selected locations to a reflecting body with flexible adhesive. The plates are supported by a platform and operatively connected to a plate driving means to effect motion of the body in a push-pull arrangement with respect to the platform. The resulting structure has a high resonant frequency even though a reflecting body in the form of relatively large glass mirror may be employed.

Light beam scanning system including piezoelectric means for correction

A three-color laser scanner using a holographically-generated plane linear grating disk (hologon). The disk includes peripherally-arranged facets having identical multiplexed diffraction gratings. Each multiplexed grating is formed from plural superimposed interference patterns accumulated by multiple exposures to light from a single monochromatic laser beam source. The multiplexed grating is optimized to diffract certain light wavelengths in a single, multichromatic (plural wavelength) input laser beam. The diffracted output beam comprises respective wavelength beam components that simultaneously scan in collinear fashion. Modulation of the plural wavelength components in the incident beam allows the output beam to scan expose a multicolor image at the image plane.
