Abstract: A portable complete analysis solution that integrates computer vision, spectrometry, and artificial intelligence for providing self-adaptive, real time information and recommendations for objects of interest. The solution has three major key components: (1) a camera enabled mobile device to capture an image of the object, followed by fast computer vision analysis for features and key elements extraction; (2) a portable wireless spectrometer to obtain spectral information of the object at areas of interest, followed by transmission of the data (data from all built in sensors) to the mobile device and the cloud; and (3) a sophisticated cloud based artificial intelligence model to encode the features from images and chemical information from spectral analysis to decode the object of interest. The complete solution provides fast, accurate, and real time analyses that allows users to obtain clear information about objects of interest as well as personalized recommendations based on the information.

Abstract: A hand-held synchronous scan spectrometer for in situ analysis of bacteria, viruses, and fungi includes a housing that contains a light source, a first monochromator positioned to receive light from the light source and operable to direct a wavelength of the light from the light source towards a sample, a second monochromator positioned to receive fluoresced light from the sample and light from first monochromator, and a detector disposed within the housing and positioned to receive light output from the second monochromator. The hand-held synchronous scan spectrometer can include a display that is integrated into the housing or can utilize a display of a removable display device (e.g., a cell phone, PDA, tablet, and the like).

Abstract: Optical systems are provided. In an embodiment, the optical system includes a first anamorphic optic having a first focal length and a first focal line, where the first focal line is parallel to a cross track direction. A second anamorphic optic has a second focal length and a second focal line, where the second focal length is different than the first first focal length. The second anamorphic optic is positioned such that the first focal line and the second focal line are in about the same location. The first and second anamorphic optics are aligned along an optical signal path, and are configured to provide afocal magnification to a signal beam along an along track direction to produce a magnified beam. A line scan imager includes an objective lens and a linear detector, and the second anamorphic optic is configured to direct the magnified beam at the objective lens.

Abstract: A printer that incorporates a spectrometry device includes a spectroscope, a distance measurer, and a spectrometry unit. The spectroscope includes a wavelength-selective interference filter on which light from a position of measurement in a medium is incident. The distance measurer measures the distance between the position of measurement and the spectroscope, and the spectrometry unit performs spectrometry at the position of measurement by using the spectroscope and correct a measured value obtained by the spectrometry based on the measured distance.

Abstract: The invention provides methods and apparatus comprising a multi-wavelength laser source that uses a single unfocused pulse of a low intensity but high power laser over a large sample area to collect Raman scattered collimated light, which is then Rayleigh filtered and focused using a singlet lens into a stacked fiber bundle connected to a customized spectrograph, which separates the individual spectra from the scattered wavelengths using a hybrid diffraction grating for collection onto spectra-specific sections of an array photodetector to measure spectral intensity and thereby identify one or more compounds in the sample.
