Abstract: An apparatus and method capable of providing spatially multiplexed IR spectral information simultaneously in real-time for multiple samples or multiple spatial areas of one sample using IR absorption phenomena requires no moving parts or Fourier Transform during operation, and self-compensates for background spectra and degradation of component performance over time. IR spectral information and chemical analysis of the samples is determined by using one or more IR sources, sampling accessories for positioning the samples, optically dispersive elements, a focal plane array (FPA) arranged to detect the dispersed light beams, and a processor and display to control the FPA, and display an IR spectrograph. Fiber-optic coupling can be used to allow remote sensing. Portability, reliability, and ruggedness is enhanced due to the no-moving part construction. Applications include determining time-resolved orientation and characteristics of materials, including polymer monolayers. Orthogonal polarizers may be used to determine certain material characteristics.

Abstract: Wavelength selection apparatus for use in various applications such as spectrometry, the demultiplexing/multiplexing of multiline laser beams, and so forth, includes an input prism and an output prism aligned along an optical axis, and at least one side mirror. A second side mirror spaced from the first side mirror on the opposite side of the optical axis may be provided, as well as end mirrors adjacent to the input and output prisms. An incoming beam incident upon the input prism is refracted so as to deflect and angularly disperse the various wavelengths present in the input beam, with the dispersing beam reflected from the first side mirror either directly to the output prism or with intermediate reflections from the second side mirror and the end mirrors before impinging upon the output prism. The output prism matches the input prism and deflects and recollimates the dispersed wavelengths to provide parallel output beams of different wavelengths spaced from one another. Selection of a desired wavelength in the output beam may be obtained by moving the input and output prisms with respect to each other axially until the desired output beam is moved to a position in which it passes through an aperture.

Abstract: A method and apparatus for detecting the presence of a specific concentration of gaseous species within a calibrated range in a gas sample is disclosed. The ILS gas detection system of the present invention simply comprises an ILS laser, a wavelength-selective optical element, and an optical detector. However, the potential or operational wavelength bandwidth of the ILS laser is preferably entirely included within one of the absorption bands or regions assigned to the intracavity gaseous species being monitored. Thus, within the calibrated range, the presence of the gaseous species changes the output laser wavelength or output intensity at a specific wavelength of the ILS laser. Consequently, only the wavelength of the output or the output intensity at the specific wavelength of the ILS laser need be monitored in order to quantitatively determine the concentration of the absorbing gaseous species within a calibrated range when using the ILS method of the present invention.
