Abstract: A Fabry-Perot resonator apparatus and method including an in-resonator polarizing element improves detection/measurement sensitivity of an optical system, provides both fields at a single end of the resonator, and overcomes other structural and performance limitations of particular optical systems. A polarizing element, which may be a quarter-wave plate, a 45-degree Faraday rotator or other polarizing element capable of converting between linear and circular polarizations and back, is placed in the resonance path of the Fabry-Perot resonator. The polarizing element effectively doubles the cavity length and orthogonally isolates forward from reverse reflection rays within the resonator, eliminating interference between rays and providing isolated bright and dark fields at each end of the resonator. The polarizing element is introduced in a lens-incorporating Fabry-Perot resonator to eliminate cross-talk between image points and is used in a non-normal incidence Fabry-Perot resonator to emit bright and dark resonance information at either end of the resonator.

Abstract: A method of determining the crystalline orientation of a crystal surface of a workpiece using Raman spectroscopy. A beam of substantially monochromatic light is directed to be incident on the crystal surface at a predetermined angle of incidence. The beam of light is substantially polarized. The workpiece is rotated relative to the beam of light about a rotation axis substantially normal to the crystal surface. A Raman shift of scattered light is measured at each of a number of rotational positions during the rotation of the workpiece. The crystalline orientation of the crystal surface is determined based on the measured Raman shifts. Data indicating the determined crystalline orientation of the crystal surface is stored.

Abstract: The image processing system is applied to dentistry, for example, and performs photography of the teeth of a patient while causing a plurality of illumination light LEDs of different wavelengths to emit light by means of a photography device when producing a crown repair or denture of the patient, whereby image data are acquired. The image data are transmitted to a dental filing system constituting a processing device where color reproduction data are determined through computation. In addition, color reproduction data are transmitted to the dental technician's office via a public switched network. Therefore, a repair material compound ratio calculation database is searched and the compound data for a material that matches the hue of the patient's teeth are found, whereby a crown repair or denture or the like that very closely matches the color of the patient's teeth is produced.

Abstract: In the color imaging system, multiple rendering devices are provided at different nodes along a network. Each rendering device has a color measurement instrument for calibrating the color presented by the rendering device. A rendering device may represent a color display in which a member surrounds the outer periphery of the screen of the display and a color measuring instrument is coupled to the first member. The color measuring instrument includes a sensor spaced from the screen at an angle with respect to the screen for receiving light from an area of the screen. A rendering device may be a printer in which the measuring of color samples on a sheet rendered by the printer is provided by a sensor coupled to a transport mechanism which moves the sensor and sheet relative to each other, where the sensor provides light from the sample to a spectrograph. The color measuring instruments provide for non-contact measurements of color samples either displayed on a color display, or printed on a sheet, and are self-calibrating by the use of calibration references in the instrument.
