Abstract: The invention provides spectroscopic systems and spectrometers employing an optical interference filter module having a plurality of bandpass regions. In certain embodiments, the systems include a mechanism for wavelength tuning/scanning and wavelength band decoding based on an angular motion of one or more filters. A spectral processing algorithm separates the multiplexed wavelength-scanned bandpass regions and quantifies the concentrations of the analyzed chemical and/or biological species. The spectroscopic system allows for compact, multi-compound analysis, employing a single-element detector for maximum performance-to-cost ratio. The spectroscopic system also allows for high-sensitivity measurement and robust interference compensation.

Abstract: An encoder spectrograph is used to analyze radiation from one or more samples in various configurations. The radiation is analyzed by spatially modulating the radiation after it has been dispersed by wavelength or imaged along a line. Dual encoder spectrographs may be used to encode radiation using a single modulator. An encoder spectrograph includes a modulator with radiation filters having non-equal widths and centered at non-equal intervals along the encoding axis of the modulator.

Abstract: The development of a multiple-channel dual phase lock-in optical spectrometer (LIOS) is presented, which enables parallel phase-sensitive detection at the output of an optical spectrometer. The light intensity from a spectrally broad source is modulated at the reference frequency, and focused into a high-resolution imaging spectrometer. The height at which the light enters the spectrometer is controlled by an acousto-optic deflector, and the height information is preserved at the output focal plane. A two-dimensional InGaAs focal plane array collects light that has been dispersed in wavelength along the horizontal direction, and in time along the vertical direction. The data is demodulated using a high performance computer-based digital signal processor. This parallel approach greatly enhances (by more than 100×) the speed at which spectrally resolved lock-in data can be acquired.

Abstract: The present invention is directed to apparatus and method for measuring the spectral characteristics of an object surface. The apparatus comprises a light source for generating an input signal comprising a plurality of wavelengths of energy and a diffraction grating for diffracting the input signal into a plurality of diffracted wavelengths of energy. A resonant mirror assembly associated with the diffraction grating sequentially directs a select diffracted wavelength to the object surface to generate a corresponding reflected wavelength of energy. The apparatus further comprises a sensor for determining each select diffracted wavelength of energy directed to the object surface and a detector for detecting one or more of the reflected wavelengths. The detector is coupled with the sensor for associating each select diffracted wavelength with each corresponding reflected wavelength.

Abstract: Apparatus for determining the temperature profile of the surface being sprayed or otherwise treated, the apparatus comprising four electric arc spray guns (1) spraying molten steel. The guns (1) are connected to a six-axis industrial robot (2) which is adapted to move them over the surface of the ceramic substrate (3). The metal deposited by the spray builds up a metal shell referred to as the sprayform. The temperature profile of the sprayform surface (3) is recorded periodically by a thermal imaging camera (4) positioned directly above the surface (3). The apparatus includes a pruning filter for receiving each pixel of an image captured by the camera (4) and for applying at least a lower temperature limit to it so as to reject or disregard any pixels determined to have a temperature less than the lower temperature limit.
