    Abstract: Apparatuses and methods to sense proximity and to detect light. In one embodiment, an apparatus includes an emitter of electromagnetic radiation and a detector of electromagnetic radiation; the detector has a sensor to detect electromagnetic radiation from the emitter when sensing proximity, and to detect electromagnetic radiation from a source other than the emitter when sensing visible light. The emitter may be disabled at least temporarily to allow the detector to detect electromagnetic radiation from a source other than the emitter, such as ambient light. In one implementation, the ambient light is measured by measuring infrared wavelengths. Also, a fence having a non-IR transmissive material disposed between the emitter and the detector to remove electromagnetic radiation emitted by the emitter. Other apparatuses and methods and data processing systems and machine readable media are also described.

    Abstract: The present invention provides a method, circuit and system for phase-sensitive detection and recovery of complex signals of interest using a double reference lock-in detector. A double reference lock-in detector may have two or more reference signal sources whose signals are first combined, producing a composite (e.g., inter-modulation) reference signal. This signal is then mixed with an input signal, yielding the desired selectivity at the frequency(ies) of interest. A second embodiment uses external reference signals, synchronizing internal references to these before combining the reference signals. Such detectors may used in chiral detection systems for recovering predetermined signals of interest associated with chiral properties of a sample being tested.

    Abstract: A method of generating a design pattern for a spatial radiation modulator to encode two or more selected spectral components in one or more spectral ranges for the chemometric analysis of a group of analytes. The method includes obtaining a corresponding spectrum for each of the analytes, defining a set of initial spectral windows, constructing a chemometric matrix to relate concentrations of the analytes to intensities of the spectral components, deriving optimized spectral windows, and translating the center wavelength and the bandwidth of each of the optimized spectral windows into a corresponding optimized annular region on the modulator.

    Abstract: The development of a multiple-channel dual phase lock-in optical spectrometer (LIOS) is presented, which enables parallel phase-sensitive detection at the output of an optical spectrometer. The light intensity from a spectrally broad source is modulated at the reference frequency, and focused into a high-resolution imaging spectrometer. The height at which the light enters the spectrometer is controlled by an acousto-optic deflector, and the height information is preserved at the output focal plane. A two-dimensional InGaAs focal plane array collects light that has been dispersed in wavelength along the horizontal direction, and in time along the vertical direction. The data is demodulated using a high performance computer-based digital signal processor. This parallel approach greatly enhances (by more than 100×) the speed at which spectrally resolved lock-in data can be acquired.

    Abstract: A system and method for a pulsed light source used in detecting fluorescence from a plurality of samples of biological material discretely, continuously or intermittently during thermal cycling of DNA to accomplish a polymerase chain reaction (PCR). An apparatus for sampling at least one sample of a biological material comprises a light source that emits a pulsed excitation light that interacts with the sample and a detector sensitive to fluorescence emitted from the sample. A method of sampling at least one sample to detect fluorescence comprises generating a pulsed excitation light with a pulsed light source; directing the pulsed excitation light into the sample; illuminating a sample with the pulsed excitation light to generate an emission light; and detecting the optical characteristics of the emission light.

    Abstract: A fluorescence subtracted Raman spectroscopy apparatus uses a wavelength modulated tunable filter as the spectrometer. The wavelength modulation results in an amplitude modulation on the detected optical signal. By using a frequency selective detection technique, the Raman signal is amplified and extracted from the fluorescence background.

    Abstract: Highly portable, handheld instrument which can be pointed at the produce to be checked. Light from a source within the instrument is directed onto the produce to induce fluorescent emission from the produce, and fluorescent emissions from the produce are monitored with a detector within the instrument to detect the presence of pesticide residue on the produce. The light from the source is filtered to selectively pass light of a wavelength which induces maximum fluorescent emission from the pesticide to be detected, and the emissions from the produce are filtered to selectively pass emissions having a spectral content characteristic of the pesticide to be detected.
