Abstract: A device, for emitting and controlling infrared light, comprises a substrate extending between a bottom surface and a top surface. A cavity is provided in the substrate, the cavity opening onto the top surface. A light source extends over the cavity and is able to heat up when passed through by an electric current, so as to emit infrared light. A cover covers the substrate, the cover and the substrate forming a first component enclosing the light source. The light source delineates a first half space comprising the cover, and a second half space comprising the cavity and the bottom surface of the substrate.

Abstract: An optical system comprises a wearable device for measuring one or more physiological parameters. The physiological parameters may change in response to stretching of the hand or movement of fingers or thumb of the user, or the parameters may be related to blood constituents or blood flow. The wearable device comprises a light source with a plurality of semiconductor diodes and a detection system that measures reflected light from tissue comprising skin. The semiconductor diodes may be light emitting diodes or laser diodes. The signal to noise ratio for the output signal may be improved by synchronizing the detection system to the light source, increasing light intensity of at least one of the plurality of semiconductor diodes from an initial light intensity, and using change detection that compares light on versus light off for the detection system output. The wearable device is also configured to identify an object.

Abstract: This invention is capable of improving performance of a biochemical analyzer and facilitating the maintenance. A light source includes: a first LED that emits ultraviolet light and a second LED that has a light emission spectrum different from that of the first LED, the first LED and the second LED being disposed in parallel; a reflection surface that is opposite to the first LED and reflects light of the first LED; and a dichroic surface that is opposite to the second LED, reflects light of the first LED, and allows light of the second LED to penetrate. When an optical member including the dichroic surface is made to be the dichroic prism, the reflection surface reflects light of the first LED to the second LED side, and by using light source of a configuration having a light shielding unit between a light emission surface of the second LED and a dichroic prism, entering of a light emitted from the plural LEDs as a one light beam (beam) to an optical system of latter stage of the biochemical analyzer is enabled.

Abstract: Apparatus and methods for complex imaging reflectometry and refractometry using at least partially coherent light. Quantitative images yield spatially-dependent, local material information about a sample of interest. These images may provide material properties such as chemical composition, the thickness of chemical layers, dopant concentrations, mixing between layers of a sample, reactions at interfaces, etc. An incident beam of VUV wavelength or shorter is scattered off of a sample and imaged at various angles, wavelengths, and/or polarizations. The power of beam is also measured. This data is used to obtain images of a sample's absolute, spatially varying, complex reflectance or transmittance, which is then used to determine spatially-resolved, depth-dependent sample material properties.

Abstract: A standoff chemical detection system that includes a source and detector are provided. The source includes: a controller, memory communicatively connected to the controller, optical sources each constructed to operate over different wavelength ranges, and a power supply. The controller controls the plurality of optical sources to emit respective infrared beams towards a target detection area in a sequential order. The detector includes: an image sensor and a controller that is communicatively connected to the image sensor. Memory and the notification device are also communicatively connected to the controller. The image sensor receives attenuated infrared beams emitted by the optical sources sequentially and at least partially attenuated by chemicals in the target detection area. The controller is constructed to calculate stimulus value signals from the recorded image data and determine whether a hazard chemical is located within the target detection area based on the calculated stimulus value signals.
