    Abstract: A discharge detection system includes a plurality of optical fibers having different optical distances from each other and provided to allow discharge light generated from a test object to enter at least one of the optical fibers, an optical sensor configured to detect the discharge light having entered the at least one of the optical fibers and to output a detection signal having a temporal change in an amplitude of the detection signal, the temporal change in the amplitude corresponding to a temporal change in intensity of the discharge light, and a signal processing system configured to identify an area where the discharge light is generated based a point of time of at least one peak in the detection signal.

    Abstract: A small scale and low cost spectral sensing system designed primarily for multi-component fluids that provides a compact, low cost platform for analyzers or chemical sensors with limited number of optical and mechanical components featuring a light source, an optical interface with the sample, and a custom detector (multi-element). A single detector element has a specific wavelength, defined by a filter that can be used to select and measure specific chemical compounds. Multiple detector elements are combined to create a multi-channel detector capable of measuring a broad range of wavelengths from ultraviolet (UV) to near and mid-infrared wavelengths. The fabricated sensor can be configured for almost any class of material including gases, vapors, and liquids, with extension to solids. This is linked to the use of the custom detectors featuring filters tailored to specific substances in a broad spectral range from the UV to infrared.

    Abstract: According to one implementation, an explosive spark estimation system includes an explosive spark estimation system includes a measuring system and a processing system. The measuring system is adapted to measure intensity of light, included in a spark occurred from an object to be tested. The light is within at least one specific wavelength band. The processing system is adapted to determine whether the spark is explosiveness based on the intensity of the light. Further, according to one implementation, an explosive spark estimation method includes: measuring intensity of light, included in a spark occurred from an object to be tested, within at least one specific wavelength band; and determining whether the spark is explosive, based on the intensity of the light.

    Abstract: Provided is a spectrum measurement apparatus including a light source configured to emit light to a sample; a light detector configured to receive light, which is reflected or scattered from, or transmitted through the sample, and to measure an intensity of the received light, and a processor configured to reconstruct a spectrum of the sample for calibration while adjusting a value of a spectrum reconstruction parameter in response to the light detector receiving the light and measuring the intensity of the received light, and to determine an optimal value of the spectrum reconstruction parameter based on a similarity between the reconstructed spectrum of the sample for calibration and an original spectrum of the sample for calibration.

    Abstract: A multi-channel measurement device for measuring properties of human tissue, may comprise a microcontroller and first and second source/sensor complexes. The first source/sensor complex may include a first housing having a first measurement portion, a first light sensor coupled to the microcontroller and exposed to the first measurement portion, and a first plurality of light sources coupled to the microcontroller and exposed to the first measurement portion. The second source/sensor complex may include a second housing having a second measurement portion, a second light sensor coupled to the microcontroller and exposed to the second measurement portion, and a second plurality of light sources coupled to the microcontroller and exposed to the second measurement portion. The first and second source/sensor complexes are coupled to each other such that the first measurement portion is opposite the second measurement portion and human tissue may be placed between the the first and second measurement portions. The microprocessor is configured with instructions stored in non-volatile memory to individually activate each of the light sources of the first and second pluralities of light sources and to record light intensity detected by the first and second light sources while an individual light source is activated. Each combination of an individually activated light source and one of the first and second light sensors provides a distinct measurement channel for measuring the absorption spectra of human blood and tissue.

    Abstract: A multidimensional spectrometer encodes frequency information into laser pulses so that a frequency insensitive detector may be used to collect data for a multi-dimensional spectrograph only from intensity information and knowledge of a modulation providing the encoding. In one embodiment the frequency encoding may be done by a conventional interferometer greatly simplifying construction of the spectrometer.
