Abstract: An optical device includes a waveplate sandwiched between first and second polarizers and is arranged to receive light emanating from an object or object image that is in motion relative to the optical device. A detector array includes one or more detector elements and is optically coupled to receive light from the second polarizer. Each detector element of the detector array provides an electrical output signal that varies according to intensity of the light received from the second polarizer. The intensity of the light is a function of relative motion of the object or the object image and the optical device and contains spectral information about an object point of the object.

Abstract: A hyperspectral/multispectral imager comprising a housing is provided. At least one light source is attached to the housing. 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.

Abstract: A method and a system for measuring an optical asynchronous sample signal. The system for measuring an optical asynchronous sampling signal comprises a pulsed optical source capable of emitting two optical pulse sequences with different repetition frequencies, a signal optical path, a reference optical path, and a detection device. Since the optical asynchronous sampling signal can be measured by merely using one pulsed optical source, the complexity and cost of the system are reduced. A multi-frequency optical comb system using the pulsed optical source and a method for implementing the multi-frequency optical comb are further disclosed.

Abstract: A method for utilizing polarization as a scheme for fluorescence removal from UV Raman spectra collected in a standoff detection scheme has been invented. In this scheme, a linearly polarized ultraviolet (UV) laser interacts with a material on a surface or in a container. The material generates Raman scattering with polarization contributions relative to that of the laser. The material possibly fluoresces as well, but the fluorescence is generally unpolarized. By subtracting a scaled version of the perpendicular component from the parallel component of the returned signal both relative to the laser source polarization—it is possible to generate a spectrum that is fluorescence free and contains the strongest features of the Raman scattered light.
