Abstract: A system and method for standoff detection of explosives and explosive residue. A laser light source illuminates a target area having an unknown sample producing luminescence emitted photons, scattered photons and plasma emitted photons. A first optical system directs light to the target area. A video capture device outputs a dynamic image of the target area. A second optical system collects photons, and directs collected photons to a first two-dimensional array of detection elements and/or to a fiber array spectral translator device which device includes a two-dimensional array of optical fibers drawn into a one-dimensional fiber stack. A spectrograph is coupled to the one-dimensional fiber stack of the fiber array spectral translator device, wherein the entrance slit of the spectrograph is coupled to the one dimensional fiber stack.

Abstract: A system and method to obtain a variable field of view (FOV) of a sample without requiring an increase in an imaging CCD array size. In a fiber array spectral translator (FAST) based chemical imaging system, the fibers in the fiber bundle may be organized in different 2D “zones”. Each zone may include a predetermined number of fibers. Each 2D zone of fibers at the signal input end is organized as a separate linear array (1D) at the spectrometer slit input end. Depending on the user-selected FOV, one or more zones of fibers may be selected for signal input (into the spectrometer) by a motorized mobile slit port or linear translating stage, which will sequentially scan output from each selected linear fiber array into the spectrometer slit. The user can switch from one FOV size to another, thereby activating the linear translating stage to gather signals from appropriate linear fiber arrays corresponding to fiber zones associated with the selected FOV. A CCD imager may be used to collect optical data and generate 2D spatially accurate wavelength resolved images of the user-selected FOV.

Abstract: Systems and methods for rapid Raman spectroscopy. The speed is improved by providing light from a sample to a light-dispersive element, such as a holographic grating, in a pattern that inversely complements distortion caused by the grating. For example, if the grating imparts a curve to the spectral lines emanating from the grating, then the light is inserted into the grating in a curve in the opposite direction. Also calibration light guides able to transmit a known, or standard, light to the detection or spectroscopy system. The calibration light guide can be useful both with traditional light transmission guides and with the light transmission guides of the present invention.

Abstract: A photometer having a plurality of input fibers to its optical entrance, at least one of which is for transmission of calibration light and at least one of which is for transmission of sample light. The exit ends of these fibers are aligned into a linear array, thereby producing an effective entrance slit for the optical entrance of the photometer. The fiber(s) for calibration light are positioned at the center of the linear array to avoid miscalibration due to photometer astigmatism.

Abstract: The invention contemplates a two-dimensional spectrometer wherein a single catadioptric system is both the collimator and the camera for two-pass use of any two-dimensionally dispersed spectrometer. Off-axis aberration effects are minimized by arranging a fiber optic as the light-entrance aperture, on the central optical axis of the spectrometer and in close proximity to or centrally inserted in a two-dimensional array detector at the image plane. In other words, the grating of the spectrometer is also a reflector which folds admitted and dispersed light for return to the image plane along essentially the same path and through the same optical elements as are used on the incoming pass of light to the diffraction grating. The invention is shown for its applicability to each of various types of two-dimensional spectrometer-design configurations.

Abstract: A dynamic light scattering apparatus (10) comprises a laser (12) optically coupled to a light scattering sample (26) via a first monomode optical fibre (18) and a first lens (22). The lens (22) produces a beam waist (24) in the sample (26), and scattered light is collected by a receive lens (30) and a second monomode optical fibre (34). The second fibre (34) has an end face in the Fourier plane (84) of the receive lens (30, 70), and defines an aperture matched to a single Airy disc (82) of the lens (30, 70). The receive fibre (34) accordingly receives a single spatial mode of light scattered from the sample (26), this mode corresponding to a single plane wave to which many scatterers contribute. The receive fibre (34) also attenuates unwanted spatial modes because of its monomode character. A photodetector (36) detects light transmitted by the receive fibre (34).
