Abstract: An infrared light source includes an emitting element extending as a radial plane about the emitting element's center and configured to heat up to emit infrared light. The emitting element lies in a cavity bounded by a cover, placed facing the emitting element. The cover has internal and external faces, the internal face facing the emitting element, and the external face defining an interface between the cover and a medium outside the light source. The cover occupies, parallel to a transverse axis perpendicular to the radial plane, a thickness, between the internal and external faces. The external face includes a planar central portion and at least one peripheral portion adjacent and inclined respective to the central portion. The planar central portion extends about the external face's center. In the peripheral portion, the cover's thickness decreases as a function of a distance from the central portion.

Abstract: Building blocks are provided for on-chip chemical sensors and other highly-compact photonic integrated circuits combining interband or quantum cascade lasers and detectors with passive waveguides and other components integrated on a III-V or silicon. A MWIR or LWIR laser source is evanescently coupled into a passive extended or resonant-cavity waveguide that provides evanescent coupling to a sample gas (or liquid) for spectroscopic chemical sensing. In the case of an ICL, the uppermost layer of this passive waveguide has a relatively high index of refraction that enables it to form the core of the waveguide, while the ambient air, consisting of the sample gas, functions as the top cladding layer. A fraction of the propagating light beam is absorbed by the sample gas if it contains a chemical species having a fingerprint absorption feature within the spectral linewidth of the laser emission.

Abstract: The invention relates generally to both a method and apparatus for the creation of full resolution color digital images of diagnostic cassettes or objects of interest using a gray-scale digital camera or sensor combined with time sequential illumination using additive primary colors followed by post exposure digital processing. Such procedures and equipment is of significant economic value when employed in situations such as diagnostic clinical analyzers where space is limited and image quality requirements are high.

Ultra-miniature SHSs in accordance with the invention, comprise a beam-splitter and gratings configured to generate a fringe pattern for spectroscopic detection. Many embodiments include input optics and a sensor and are configured in a way to omit collimating optics and imaging optics from the SHS. Compared to conventional SHSs known in the art, the present invention enables fewer parts, significantly smaller and lighter SHSs, are more efficient and robust, and require less maintenance. Many embodiments are field-deployable, in that such embodiments can be deployed for hand held use in real-world or remote activities outside of research or diagnostic facilities.

Abstract: A device for determining the surface topology and associated color of a structure, such as a teeth segment, includes a scanner for providing depth data for points along a two-dimensional array substantially orthogonal to the depth direction, and an image acquisition means for providing color data for each of the points of the array, while the spatial disposition of the device with respect to the structure is maintained substantially unchanged. A processor combines the color data and depth data for each point in the array, thereby providing a three-dimensional color virtual model of the surface of the structure. A corresponding method for determining the surface topology and associate color of a structure is also provided.

Abstract: Crop is routed past a sample window on an agricultural combine harvester. Light it is impinged on the crop from an illumination source and reflected radiation is directed to a sensor. The output of the sensor is indicative of various constituents in the harvested crop. The illumination source is controlled based on the temperature proximate the crop sample.
