Abstract: A spatial Fourier transform spectrometer is disclosed. The Fourier transform spectrometer includes a Fabry-Perot interferometer with first and second optical surfaces. The gap between the first and second optical surfaces spatially varies in a direction that is orthogonal to the optical axis of the Fourier transform spectrometer. The Fabry-Perot interferometer creates an interference pattern from input light. An image of the interference pattern is captured by a detector, which is communicatively coupled to a processor. The processor is configured to process the interference pattern image to determine information about the spectral content of the input light.

Abstract: An active remote sensing system is provided with an array of laser diodes that generate light directed to an object having one or more optical wavelengths that include at least one near-infrared wavelength between 700 nanometers and 2500 nanometers. One of the laser diodes pulses with pulse duration of approximately 0.5 to 2 nanoseconds at repetition rate between one kilohertz and about 100 megahertz. A beam splitter receives the laser light, separates the light into a plurality of spatially separated lights and directs the lights to the object. A detection system includes a photodiode array synchronized to the array of laser diodes and performs a time-of-flight measurement by measuring a temporal distribution of photons received from the object. The time-of-flight measurement is combined with images from a camera system, and the remote sensing system is configured to be coupled to a wearable device, a smart phone or a tablet.

Abstract: A wearable device includes a measurement device adapted to be placed on a wrist or ear having a light source with LEDs to measure physiological parameters. The measurement device generates an optical beam having a near infrared wavelength between 700-2500 nanometers by modulating the LEDs, and lenses to deliver the beam to tissue, which reflects the beam to a receiver having spectral filters in front of spatially separated detectors coupled to analog to digital converters that generate at least two receiver outputs. Signal-to-noise ratio of the beam reflected from the tissue is improved by comparing the receiver outputs, and by increasing light intensity from the LEDs. The receiver is synchronized to the modulation of the LEDs and uses a lock-in technique that detects the modulation frequency. The measurement device generates an output signal representing a non-invasive measurement on blood within the tissue.

Abstract: Integrated computational elements having alternating layers of materials may be problematic to configure toward mimicking some regression vectors. Further, they sometimes may be inconvenient to use within highly confined locales. Integrated computational elements containing a quantum dot array may address these issues. Optical analysis tools with an integrated computational element can comprise: an electromagnetic radiation source that provides electromagnetic radiation to an optical pathway; an integrated computational element positioned within the optical pathway, the integrated computational element comprising a quantum dot array having a plurality of quantum dots disposed at a plurality of set array positions; and a detector that receives the electromagnetic radiation from the optical pathway after the electromagnetic radiation has optically interacted with a sample and the integrated computational element. Optical interaction of electromagnetic radiation with the quantum dots at one or more set array positions can substantially mimic a regression vector for a sample characteristic.

Abstract: An apparatus for measuring a wavelength-dependent optical characteristic of an optical system has a light-pattern generation device which generates a pattern of polychromatic light in an object plane. Together with the optical system, a measuring optical unit images the object plane on a spatially resolving light sensor. A dispersive optical element is arranged in a light path between the optical system and the light sensor in such a way that a plurality of images of the pattern with different wavelengths are generated simultaneously on the light sensor. The evaluation device determines the wavelength-dependent characteristic of the optical system from the plurality of images on the light sensor.

Abstract: Provided are a Raman signal measuring method and apparatus which use a difference in a time scale between Raman scattered light and fluorescence. Thus, after exciting light is incident upon a target object, light scattered from the target object may be detected before the target object generates fluorescence in response to the exciting light. As a result, a Raman signal in which background fluorescence is reduced may be obtained.
