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.

Abstract: The present invention is directed to a monochromator device which uses single grating volume holograms. The holograms collect light of varying wavelengths such as polychromatic light, and separate one particular wavelength of interest. A wide wavelength spectrum can be targeted, either by angularly tuning the holograms, or by using an array of holograms each of which is tuned to a different center wavelength. The large aperture and high angular dispersion of the volume holograms provides a higher light throughput than that of prior art monochromators. The present invention can be used anywhere that efficient separation of polychromatic light into its narrowband components is required. The monochromator may be placed immediately before a light source, or before other optical or signal processing devices to provide the filtered wavelength of light input to such devices.

Abstract: An optical apparatus in which multiplexed holograms are used to achieve wavelength selectivity and polarization manipulation is used to facilitate near-normal incidence of light on the holograms. The polarization manipulation allows light reflected from the holograms to be separated from the light incident on the holograms. In one application, the apparatus can be used to extract spectral lines of an analyte from radiation scattered from a sample.

Abstract: A holographic imaging spectrometer, apparatus, and/or method enables the projection of a two-dimensional (2D) slice (having spectral information) of a four-dimensional (4D) probing object. A 4D probing source object is illuminated to emit an optical field. A holographic element having one or more recorded holograms receives and diffracts the optical field into a diffracted plane beam having spectral information. Collector optics (e.g., an imaging lens) focuses the diffracted plane beam having spectral information to a 2D slice (having spectral information) of the 4D probing source object. The focused 2D slice having spectral information is projected onto a 2D detector array surface. In addition, the holographic element may have multiple multiplexed holograms that are arranged to diffract light from the corresponding slice of the 4D probing source object to a non-overlapping section of the detector.

Abstract: A volume-phase holographic diffraction grating device is provided that can be optimized for use with very short wavelength light, such as light in the ultraviolet (UV) spectral region. The device comprises a cover and a substrate, both formed of a glass material. A layer of gelatin material is disposed between the cover and the substrate member, and has holographically-formed varying indexes of refraction formed therein to set up the interference pattern. The gelatin material has a thickness between 0.5 and 1 micron that makes it suitable for diffracting light in the UV spectral region, long-lived, and very efficient.
