Abstract: The disclosure relates to a portable and/or handheld bioagent detector and methodology described herein that is based in part on advanced Raman Chemical Imaging (“RCI”) technology. According to one embodiment of the present disclosure, the detection system may include a fiber array spectral translator (“FAST”) and may also include a probe which may include a complementary metal oxide semiconductor (CMOS) camera. The probe alleviates the need to place the main instrument close to an unconfined release of a potentially hazardous material and facilitates analysis of a sample that is situated in a hard-to-reach location while minimizing contamination of the detector and operator.

Abstract: To achieve a given spectral resolution with reduced detector size and commercially available pixel pitches, the Raman spectrum is shifted across the detector array such as by one of the following methods: 1) tuning the excitation wavelength; 2) rotating the grating; 3) displacing the effective input slit (fiber) and acquiring the spectrum under stepped displacement conditions; and 4) displacement of a lens relative to input fiber to displace effective input slit relative to the detector. A composite spectrum is formed and deconvolution of the entrance aperture image and/or pixel masking is then used.

Abstract: A spectrometer has a source of illumination radiation having a plurality of spectral wavelengths, a bandpass filter, a dispersive beamsplitter disposed in an optical path of said source of illumination radiation, an illumination radiation rejection filter, and a spectrograph disposed in a path of radiation from a sample illuminated by illumination radiation from said source of illumination radiation. The dispersive beamsplitter, the bandpass filter, the illumination radiation rejection filter and spectrograph are tunable in correspondence to a selected one of the plurality of spectral wavelengths of the source of illumination radiation. The dispersive beamsplitter directs the selected one of the plurality of spectral wavelengths of illumination radiation to a sample and directs elastically scattered and reflected radiation from the sample out of a measurement beam of light emanating from the sample. The inelastically scattered light passes through the dispersive beamsplitter essentially unaffected and is directed to the illumination radiation rejection filter and the spectrograph.

Abstract: For identifying black plastics effectively and rapidly, it is desirable to maintain full laser power while reducing the power density. This is achieved by the incorporation of a moving lens that disperses the 0.5mm laser spot over a larger area typically of about 5mm in diameter. The entire signal from the larger (5mm) diameter is collected at the same spot in the fiber bundle leading to a Raman or other spectral analyzer. There are no other modifications required for the rest of the system as the moving lens does not affect the collection efficiency of the characteristic signal from the sample.
