Abstract: A common aperture, multi-mode optical imager for imaging electromagnetic radiation bands from a field of two or more different wavelengths is described. Fore-optics are provided to gather and direct electromagnetic radiation bands forming an image into an aperture of the multi-mode optical imager. The image is divided into two different wavelength bands, such as visible light and long-wave infrared. The first wavelength band (e.g., visible light) is detected by a first detector, such as a CCD array, for imaging thereof. The second wavelength band (e.g., long-wave infrared) is detected by a second detector, such as an uncooled microbolometer array, for imaging thereof. Additional optics may be provided for conditioning of the first and second wavelength bands, such as such as for changing the magnification, providing cold shielding, filtering, and/or further spectral separation.

Abstract: An apparatus and method capable of providing IR spectral information using IR absorption phenomena requires no moving parts or Fourier Transform during operation. IR spectral information and chemical analysis of a sample in a sample containing functional groups is determined by using an IR source, a sampling accessory for positioning the sample volume, an optically dispersive element, a focal plane array (FPA) arranged to detect the dispersed light beam, and a processor and display to control the FPA, and display an IR spectrograph. Fiber-optic coupling allows remote sensing, and portability, reliability, and ruggedness is enhanced due to the no-moving part construction. Use of the apparatus and method has broad industrial and environmental application, including measurement of thickness and chemical composition of various films, coatings, and liquids, and may also be used in real-time sensing of hazardous materials, including chemical and biological warfare agents.

Abstract: The present invention concerns an LED spectrometer operating without moving parts according to the sweep principle, and appropriate to serve as a structural component in many kinds of spectroscopic concentration analyzers. The design of the invention affords the advantage that, even at its minimum, the optical power of the LED spectrometer of the invention is about fivefold compared with the designs of prior art. Furthermore, improvement of the efficiency of the LED radiation source and of that of the optics has brought a multiple augmentation in power to the wavelength spectrum sent out by the radiation source. In the design of the invention, concentrators (6) of non-imaging type are used to collimate the wavelength spectrum emitted by the LEDs (3).
