Abstract:
Aspects of a tandem dispersive range monochromator and data knitting for the monochromator are described herein. In one embodiment, the monochromator includes a tandem diffraction grating, a grating drive motor that rotates the tandem diffraction grating to provide, by diffraction of broadband light, first dispersed wavelengths of light and second dispersed wavelengths of light, a detector that detects a first reflection from the first dispersed wavelengths of light and a second reflection from the second dispersed wavelengths of light, and processing circuitry that knits together data values from the first reflection and data values from the second reflection to provide a spectrum of combined data values. By using a tandem diffraction grating having different dispersive surfaces, measurements of relatively high precision and quality may be taken throughout a wider spectral range, and the measurements may be knitted together to provide a spectrum of combined data values.

The present invention provides a method of digitally generating, via the use of a computer, data indicative of a synthesized appearance of a simulated material having physically plausible appearance attributes. The method includes determining a set of data indicative of the synthesized appearance of the simulated material based at least in part on data associated with the physically tangible source material and at least in part on data of measured attributes of the physically tangible reference material.
Abstract:
A movable carriage includes a mechanism configured to hold a sensor unit so as to allow the sensor unit to displace with respect to the carriage. The mechanism allows the sensor unit to displace with respect to the carriage in a rotational direction centering on a shaft parallel to a moving direction of the carriage and disposed above a reading area of the sensor unit, and in a vertical direction.

Abstract:
An optical emission spectroscopic (OES) instrument includes a spectrometer, a processor and an adjustable mask controlled by the processor. The adjustable mask defines a portion of an analytical gap imaged by the spectrometer. The instrument automatically adjusts the size and position of an opening in the mask, so the spectrometer images an optimal portion of plasma formed in the analytical gap, thereby improving signal and noise characteristics of the instrument, without requiring tedious and time-consuming manual adjustment of the mask during manufacture or use.

A wavelength-variable interference filter includes first and second electrodes provided at first and second substrates, respectively, the second substrate including a movable section, first and second electrode wires that extend from the first and second electrodes toward outer circumferential edges of the first and second substrates, respectively, a first opposite electrode wire disposed so as to be isolated from the second electrode, and a first conductive section that connects the first electrode wire with the first opposite electrode wire. The second electrode wire and the first opposite electrode wire extend passing through a center point of an imaginary circle of the movable section in respective directions and dividing the imaginary circle at regular angular intervals.

Abstract:
An apparatus for placement on or in a body of water for hyperspectral imaging of material in the water comprises an artificial light source and a hyperspectral imager. These are arranged so that in use light exits the apparatus beneath the surface of the water and is reflected by said material before re-entering the apparatus beneath the surface of the water and entering the hyperspectral imager. The hyperspectral imager is adapted to produce hyperspectral image data having at least two spatial dimensions.
