    Abstract: 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.

    Abstract: An optical power limiter comprises an input optical transmission element, an output optical transmission element, and a power-limiting element disposed between the input and output elements for transmitting optical signals from the input element to the output element. The power-limiting element comprises an optical-limiting solid mixture containing particles of at least one material that produces reversible thermal changes in response to light above a predetermined optical power level, thereby changing the optical transmission properties of the power-limiting element.

    Abstract: A scanner device includes a color measuring, a support surface for a measured object and a drive unit for moving the measuring head across the support surface and for adjusting the height of the measuring head in a direction perpendicular to the support surface. The measuring head is equipped with an illuminating channel and a collection channel. The illuminating channel has a light source and optical means for illuminating the measured object at a measurement site at a mean angle of incidence of 45°. The collection channel has optical means for capturing light emanating from the measured object at the measurement site at a mean collection angle of 0° and coupling it into a light guide, which directs the captured light to a wavelength-selective photoelectric transformer, which resolves it into a number of wavelength ranges and generates an electric measurement signal corresponding to each wavelength range.

    Abstract: The present invention relates to a method and system of array imaging that extends or maximizes the longevity of the sensor array by minimizing the effects of photobleaching. The imaging system has a light source, a variable exposure aperture, and a variable filter system. The system extends the longevity of sensors by (1) using the variable exposure aperture to selectively expose sections of the sensor array containing representative numbers of each type of sensor, and/or (2) using the variable filter system to control the intensity of the excitation light, providing only the intensity required to induce the appropriate excitation and increasing that intensity over time as necessary to counteract the effects of photobleaching.

The illuminating channel (IC) has a light source (10) and optical means (12-22) for illuminating the measured object (S) at a measurement site at a mean angle of incidence of 45 E. The collection channel (CC) has optical means (24-34) for capturing the light emanating from the measured object at the measurement site at a mean collection angle of 0 E and coupling it into a light guide (LF), which directs the captured measurement light to a wavelength-selective photoelectric transformer preferably provided in the form of a spectrometer, which resolves it into a number of wavelength ranges and generates an electric measurement signal corresponding to each wavelength range. The color measuring head is suitable for taking high-precision measurements of even the smallest measurement fields without contact.

    Abstract: A color sensor for measuring light from a light source and the method for fabricating the color sensor. The color sensor includes a plurality of photodetectors, a plurality of primary color filters and a trim filter. Each primary color filter includes a layer of material between the light source and a corresponding one of the photodetectors. Each primary color filter preferentially transmits light in a corresponding band of wavelengths about a characteristic wavelength. The trim filter is located between the light source and the photodetectors and includes a layer of material that preferentially attenuates light at a first trim wavelength between two of the characteristic wavelengths. In one embodiment, the trim filter further preferentially attenuates light at a second trim wavelength, the first wavelength being less than one of the characteristic wavelengths and the second wavelength being greater than that characteristic wavelength.
