    Abstract: The wavelength of a spectrometer is calibrated by using a commercial Ho glass filter. The spectrometer includes a light source including a D2 lamp and not including a mercury lamp, and a reference wavelength input unit for inputting, as a reference wavelength, a wavelength of a specific absorption peak separately measured for an Ho glass filter to be used. To calibrate the wavelength of the spectrometer by using the wavelength of a specific emission line peak of the D2 lamp and the reference wavelength input by the reference wavelength input unit, the wavelength calibration unit holds a conversion table showing a theoretical relationship between the number of control pulses for rotating a diffraction element and the corresponding wavelength of diffracted light, and calibrates the number of control pulses from the conversion table by the wavelength calibration unit.

    Abstract: The present invention is a method of obtaining and isolating sample spectra from a wide wavelength illumination source without the use of filters. The method obtains the combined sample and illumination spectra of a sample and removes the illumination spectrum from the combined spectrum. This is accomplished by obtaining both the combined sample/illumination spectrum and the illumination spectrum separately at the same time and under the same environmental and instrument conditions. The illumination spectrum is then subtracted, wavelength by wavelength from the combined sample/illumination spectrum, leaving the pure sample spectrum which may a single spectrum or combination of two or more spectra from different types and/or compounds in the sample.

A micromirror arrangement is provided in this plane, and a spectrally selective change in direction of the detection beam is carried out by controlling the micromirrors, where a useful light component of the detection beam arrives on a detector. At least one second micromirror arrangement and a 1:1 imaging of the first micromirror arrangement in the second micromirror arrangement is provided. Alternatively, the same micromirror arrangement is passed at least twice, where, in the light path between the first pass and second pass, a spatial offset of the light beam of at least the first pass and second pass is generated on the micromirror arrangement by optical means.

The system in one embodiment includes: a light source; a plurality of cold mirrors configured to direct light along a beam path; a cold or warm sample holder in the beam path; windows of sample holder (or whole sample holder) are transparent in a spectral region of interest, so they do not emit thermal radiation in the same spectral region of interest; a cold monochromator or other cold spectral device configured to direct a selected fraction of light onto a cold detector; a system of cold apertures and shields positioned along the beam path to prevent unwanted thermal radiation from arriving at the cold monochromator and/or the detector; a plurality of optical, IR and microwave filters positioned along the beam path and configured to adjust a spectral composition of light incident upon the sample under investigation and/or on the detector; a refrigerator configured to maintain the detector at a temperature below 1.0K; and an enclosure configured to: thermally insulate the light source, the plurality of mirrors, the sample holder, the cold monochromator and the refrigerator.

    Abstract: A fiber grating sensor system is used to measure key parameters that include pressure, strain and temperature at specific locations and at high speed. The system relies on spectral properties associated with the fiber grating sensors, the light source and the optical detection system to provide these capabilities. The system has been successfully applied to measurement of pressures up to 1,200,000 psi and by increasing the spectral width of the light source extensions of pressure measurements to 4,000,000 psi and higher are possible. Temperature change measurements have been made of 400 degrees C. over a period of 25 micro-seconds limited by the physical response of the fiber sensors and the output detector bandwidth both of which can be greatly improved by reducing fiber sizes and with improved detectors. Novel methods have been devised to lower cost and enable measurements with spatial location, speed and accuracy that have been very difficult or not yet achieved.
