  • Publication number: 20100292581
    Abstract: A dynamically calibrating optical spectrometer and method for dynamically calibrating the optical spectrometer are provided. The optical spectrometer may include a band-pass device and a device that scans, such that a scan window can be widened, and the edges of the band-pass device can be used to calibrate out drifts in the system. The optical spectrometer may be for acquiring and analyzing a spectroscopic sample of an analyte from a sampling region of the tissue of a person. The optical spectrometer includes a tunable source of electromagnetic radiation, a probe for delivering the electromagnetic radiation to the tissue at the sampling region and obtaining a diffuse reflectance signal from the tissue at the sampling region, a spectroscopic detector for analyzing the diffuse reflectance signal for presence of the analyte, and a wavelength calibration detector for calibrating the tunable source of electromagnetic radiation to a desired wavelength.

  • Patent number: 7283181
    Abstract: A display system is configured to produce a color image formed of a plurality of differently colored images and may include at least one light source that directs light along an optical path, and at least one filter having a given optical filter characteristic. The display system may be selectively operable in a first state in which the optical path does not pass through a first filter during production of the plurality of differently colored images to form a color image having a first optical characteristic, and in a second state in which the optical path passes through the first filter during production of the plurality of differently colored images to form a color image having a second optical characteristic different than the first optical characteristic.

  • Patent number: 7170697
    Abstract: A programmable waveform ballast has a power supply and a waveform generator. The power supply provides, from a power source, a variable power to a discharge lamp. The waveform generator is coupled to the power supply and is programmable to produce a plurality of waveforms. The waveform generator controls the power supply to apply the variable power to the discharge lamp in accordance with a programmed waveform.

  • Patent number: 7103896
    Abstract: An optical disc of one embodiment of the invention is disclosed that includes a first surface, a second surface, an optically writable label area, and an optically writable data area. The first and the second surfaces are oppositely situated to one another. The label area is on one of the first and the second surfaces. The data area is on one of the first and the second surfaces. The mechanism aids proper focusing of an optical beam of an optical disc device on the optically writable label area and on the optically writable data area.

  • Patent number: 7046419
    Abstract: A digital micromirror device arrangement and devices using the arrangement are disclosed. The arrangement includes a digital micromirror device (DMD) having an active area, a cover plate disposed substantially adjacent to the DMD and having a thickness and a light blocking area having an aperture formed therein. The active area is adapted to receive incoming light and to reflect the incoming light as outgoing light. The light-blocking layer is offset from a plane of the active area by at least the thickness of the cover plate and is adapted to block light from passing therethrough. The aperture is dimensioned to produce a beam of outgoing light having desired dimensions.

  • Patent number: 6964484
    Abstract: A technique is described to reduce overfill of light that has exited a light integrating device and is applied to an optical modulator in the form of an illuminating pattern. The illumination reduction technique makes the illuminating pattern more closely conform to a active planar surface of the optical modulator by at least partially providing anamorphic magnification of the illuminating pattern.

  • Publication number: 20040212546
    Abstract: A method for color management in a display system based on perception. A plurality of images may be displayed to a viewer using an additive display device. Each image of the plurality may have a different color adjustment and at least two colors. An input may be received from the viewer selecting an image of the plurality based on the viewer's color perception of such image relative to other images of the plurality. Subsequent images may be displayed according to the different color adjustment of the image selected.
