Abstract: Disclosed is a process and device that enables ultra-high resolution one- and two-dimensional spatial imaging of Rayleigh, Raman and Thomson spectral features without the need for a spectrometer. The disclosed approach provides the capability for imaging of a single spectral feature such as a single rotational Raman line and the simultaneous elimination of background scattering, or for separating the rotational Raman image from the Rayleigh scattering. High collection efficiency provides the opportunity for single pulse time frozen images to be acquired.

Abstract: Hyperspectral imaging is carried out by utilizing a set of lasers to illuminate a scene containing a sample in a series of successive laser illuminations by turning on at least one laser in the set of lasers for each successive illumination in the series. Here, each laser generates a known wavelength of light. Imaging is further carried out by utilizing a camera to capture an image of the scene during each successive laser illumination, thus generating a series of successive images. However, no dispersive element is utilized between the scene and the camera. Imaging is still further carried out by processing the captured images to produce scene data. The scene data is compared with target profiles to determine whether the scene includes at least one target of interest and taking a predetermined action in response to detecting at least one target of interest.

Abstract: A system for remotely detecting gas concentration is provided. The system includes a plurality of light sources. At least a first one of the light sources generates light having a first wavelength and a first polarization, and at least a second one of the light sources generates light having a second, different wavelength and a second polarization that is orthogonal to the first polarization. The light from the light sources is placed on a common transmission path, and is directed to a target area by a steering mirror. Light reflected from the target area is received and directed to a detector. The detector provides information regarding the time of arrival and amplitude of the received light, allowing range and gas concentration information to be obtained. In some embodiments the detector is an imaging detector, allowing three-dimensional range information to be obtained from the target area from a single light pulse.

An objective lens, in an optical communication path comprising originating and terminating ends, is further attached to the housing and causes light to (i) be backscattered by the tissue of a subject at the originating end and then (ii) pass through the objective lens to a beam steering element at the terminating end of the communication path inside the housing. The beam steering element has a plurality of operating modes each of which causes the element to be in optical communication with a different optical detector in a plurality of optical detectors offset from the optical communication path. Each respective detector filter in a plurality of detector filters covers a corresponding optical detector in the plurality of optical detectors thereby filtering light received by the corresponding detector from the beam steering element.
