    Abstract: Systems capable of acquiring polarimetry data using a single camera with or without a polarizing filter. When a polarizing filter is used, the data acquisition method comprises: (1) maneuvering the aircraft (or other vehicle) to orient the polarizing filter (and camera) in various directions when images are captured, (2) registering the various images to each other, and (3) computing polarimetry values (such as the Stokes parameters) for points of interest in the images. When a polarizing filter is not used, the data acquisition method comprises maneuvering the aircraft (or other vehicle) to orient the camera in various directions when images are captured and then performing the same operations (2) and (3). These methods measure the amount of polarization in a given scene by taking multiple camera images at different angles.

    Abstract: The present invention is thus directed to an automated system of varying the optical path length in a sample that a light from a spectrophotometer must travel through. Such arrangements allow a user to easily vary the optical path length while also providing the user with an easy way to clean and prepare a transmission cell for optical interrogation. Such path length control can be automatically controlled by a programmable control system to quickly collect and stores data from different path lengths as needed for different spectrographic analysis. Moreover, the system utilizes configured wedge shaped windows to best minimize the reflections of light which cause periodic variation in transmission at different wave lengths (commonly described as “channel spectra”). Such a system, as presented herein, is able to return best-match spectra with far fewer computational steps and greater speed than if all possible combinations of reference spectra are considered.

    Abstract: An autofocus Raman spectrometer system includes a laser probe assembly, a microprocessor, adjustable stages and a driving means. The laser probe assembly includes an excitation means, a focusing optics provided to focus an excitation beam from the excitation means onto a sample and generate Raman scattering spectrum, a collection optics for collecting the Raman scattering spectrum, and a spectrographic detector for generating a Raman spectrum based on the Raman scattering intensity received from the collection optics. The microprocessor receives the Raman spectra signal therefrom. The laser probe assembly is situated on the adjustable stage. The driving means is coupled to the microprocessor and configured to drive the stage to move with respect to the sample. The microprocessor generates a command to the driving means for moving a position of the adjustable stage to achieve an optimal optical focus based on signal intensity of the spectra peaks measured by the spectrographic detector.
