    Abstract: A portable spectrometer device includes an illumination source for directing at a sample, and a tapered light pipe (TLP) for capturing light interacting with the sample at a first focal ratio and for delivering the light at a second focal ratio lower than the first focal ratio. A linearly variable filter (LVF) separates the captured. light into a spectrum of constituent wavelength signals; and a detector array, including a plurality of pixels, each of the plurality of pixels disposed to receive at least a portion of a plurality of the constituent wavelength signals provides a power reading for each constituent wavelength. Preferably, the TLP is lensed at one end, and recessed in a protective boot with stepped inner walls. The gap between the TLP and LVF is minimized to further enhance resolution and robustness.

    Abstract: An approach to noninvasively and remotely detect the presence, location, and/or quantity of a target substance in a scene via a spectral imaging system comprising a spectral filter array and image capture array. For a chosen target substance, a spectral filter array is provided that is sensitive to selected wavelengths characterizing the electromagnetic spectrum of the target substance. Elements of the image capture array are optically aligned with elements of the spectral filter array to simultaneously capture spectrally filtered images. These filtered images identify the spectrum of the target substance. Program instructions analyze the acquired images to compute information about the target substance throughout the scene. A color-coded output image may be displayed on a smartphone or computing device to indicate spatial and quantitative information about the detected target substance. The system desirably includes a library of interchangeable spectral filter arrays, each sensitive to one or more target substances.

    Abstract: A modular device includes base and color sensing portions. The color sensing portion has a face, a controlled light source having a first channel between the light source and the face, and a color sensor arranged at a distal end of a second channel. The color sensor receives light reflected from the target surface and generates output signals representative of a surface color. The first and second channels extend at least 45 degrees apart from each other and respective to the face. The base portion communicates with the color sensor and a user interface enabling control input for the color sensor. The program further receives the output signals from the color sensing device and displays a first image of the detected color, and displays a second image of a user-selected color beside the first image. Color data values are further displayed corresponding to the difference between displayed colors.

    Abstract: A device (1) for analysing the material composition of an object (2) has a casing (3) with a handle (4), an operating trigger (5), a window (6) for abutment against the object to be analysed and a display (7) for displaying the analysis of the object. Mounted in the casing is a housing (11) having a base (12) to which it is pivotally connected about an axis (14) at one end (15). At the other end (16), a stepper motor (17) is provided for traversing the end across the base. This end has an opening (18) generally in alignment with an opening (19) in the housing in which the window is mounted. Within the housing, are mounted: a laser diode (21); a laser amplification crystal (22); a collimating lens (23); a laser focusing lens (24). The components are arranged on a laser projection axis (25), which passes out through the openings (18,19). A plane mirror (32) can receive light emitted by a plasma P excited at the surface of the object (2). Light from the plasma P is reflected in the direction (34) across the projection axis to a curved focusing mirror (35). From this mirror, the light is reflected again across the projection axis and focused on the end of an optical (fibre (37) set in an aperture (38) in the side wall (39) of the housing opposite from the reflecting mirror.
