    Abstract: A sensing apparatus consisting of more than one diode laser having select lasing frequencies, a multiplexer optically coupled to the outputs of the diode lasers with the multiplexer being further optically coupled to a pitch side optical fiber. Multiplexed laser light is transmitted through the pitch side optical fiber to a pitch optic operatively associated with a process chamber which may be a combustion chamber or the boiler of a coal or gas fired power plant. The pitch optic is oriented to project multiplexed laser output through the process chamber. Also operatively oriented with the process chamber is a catch optic in optical communication with the pitch optic to receive the multiplexed laser output projected through the process chamber. The catch optic is optically coupled to an optical fiber which transmits the multiplexed laser output to a demultiplexer. The demultiplexer demultiplexes the laser light and optically couples the select lasing frequencies of light to a detector with the detector being sensitive to one of the select lasing frequencies.

    Abstract: A convenient and economical method and instrumentation to efficiently reduce offensive spectral noises due to water vapor and carbon dioxide gas often encountered in FTIR spectrophotometry is provided by spectrally monitoring and controlling the amount of water vapor and carbon dioxide gas inside the spectrophotometer such that both amounts in the sample and background measurements become congruent through remote open-close operation of water-vapor (or carbon dioxide gas) supplier and dehumidifier (or carbon dioxide gas adsorber). This new technique can be used: (1) Under the ambient humidity condition, saving time and money effectively. (2) Both in the closed spectrophotometer and in the open system. (3) And applicable to any FTIR accessory and measurement method, including transmission, external reflection, reflection-absorption, attenuated total reflection (ATR), and microscopy measurements.

    Abstract: A compact imaging spectrometer comprises an entrance slit, a catadioptric lens with a mirrored surface, a grating, and a detector array. The entrance slit directs light to the mirrored surface of the catadioptric lens; the mirrored surface reflects the light back through the lens to the grating. The grating receives the light from the catadioptric lens and diffracts the light to the lens away from the mirrored surface. The lens transmits the light and focuses it onto the detector array.

    Abstract: The embodiments disclosed herein generally relate to identifying and removing background noise in spectroscopic imaging of a sample. Because white-light has essentially constant intensity at every wavelength, background noise caused by white light can be identified and removed from spectroscopic measurements including Raman spectroscopy. Thus, once the Raman spectrum for a sample is obtained, it may be corrected to remove the white-light dispersive spectrum in accordance with the embodiments disclosed herein.

    Abstract: This invention relates to an accessory for incorporation into Raman and other spectroscopic instruments for combining shuttering and spectroscopic calibration functions. The accessory is comprised of an assembly with at least two positions that may be inserted into the light path, one position allowing light to be directed to and from the sample, and another position containing a reference standard that blocks the beam and provides a shuttering function. When the light strikes the reference standard, a reference spectrum is produced that may be used to calibrate the spectrograph. The device is especially useful in combination with compact sampling accessories for Raman spectroscopy.

    Abstract: Described herein is a wavelength reference device comprising a housing defining an internal environment having a known temperature. A broadband optical source is disposed within the housing and configured to emit an optical signal along an optical path. The optical signal has optical power within a wavelength band of interest. An optical etalon is also disposed within the housing and positioned in the optical path to filter the optical signal to define a filtered optical signal that includes one or more reference spectral features having a known wavelength at the known temperature. The device also includes an optical output for outputting the filtered optical signal.
