Abstract: Systems and methods of the present disclosure are directed to detecting species within a fluid using a multi-pass absorption cell and a spectrometer. The absorption cell includes a plurality of mirrors arranged in a manner such that a detection light traverses multiple passes through the fluid within the absorption cell. In some implementations, the detection light is reflected by the plurality of mirrors to form optical paths in more than one plane. The system also includes an electronic unit configured to receive and process spectral data from the spectrometer. In some implementations, the electronic unit communicates with at least one computational unit over a communication interface to send a portion of the spectral data for processing. The electronic unit may also receive processed data from the computational unit.

Abstract: A measurement system comprises a pulsed laser diode array that includes one or more Bragg reflectors, and wherein the light generated by the array penetrates tissue comprising skin. At least some of the wavelengths of light are in the near infrared. The detection system is synchronized to the laser diode array and comprises an infrared camera and a first receiver comprising a plurality of detectors. The first receiver comprises one or more detector arrays and performs a time-of-flight measurement. The measurement system generates an image, the detection system non-invasively measures blood in blood vessels within or below a dermis layer within the skin based at least in part on near-infrared diffuse reflection from the skin, and the detection system measures absorption of hemoglobin between 700 and 1300 nanometers wavelength range. A processor compares the absorption of hemoglobin between different tissue spatial locations, and the measurement system processes the time-of-flight measurement.

Abstract: Embodiments are disclosed for terahertz spectroscopy and imaging in dynamic environments. In an embodiment, a transmitter of an electronic device emits a continuous electromagnetic (EM) wave in the terahertz (THz) frequency band into a dynamic environment that includes a transmission medium that changes over time. A receiver of the electronic device, receives an EM wave reflected off an object in the environment and determines a spectral response of the reflected EM wave. The spectral response includes absorption spectra at a frequency in the THz frequency band that is indicative of a known target transmission medium. The absorption spectra of the target transmission medium and a path length of the reflected EM wave signal are used to obtain the concentration level of the target transmission medium from a reference library of known concentration levels.

Abstract: A compact mmW spectroscopy cell system for detecting volatile organic compounds (compounds) in a gas. The system includes a gas collection chamber, an input buffer cavity for receiving the gas from the gas collection chamber, pumping devices to pass the gas from the buffer cavity to an absorption cell and maintain pressure, and a transceiver connected to the cell. The transceiver interrogates the absorption cell filled with the gas by passing a high frequency electromagnetic signal and sweeping the signal to generate an absorption spectra which is compared to a spectroscopy database for detecting the compounds in the gas. The absorption cell, collection chambers, and pumping devices are fabricated with standard CMOS processing techniques at chip and wafer scale. The transceiver bonded to the absorption cell with chip scale integration.

Abstract: A reflectometer has a depth sensor which obtains distance information between the depth sensor and an object, a light source which emits light having a calibrated light spectrum, a spectral sensor which collects spectral information from light reflected from the object, and a circuitry. The circuitry calculates a reflectance spectrum for the object based on the distance information and the spectral information collected from light being reflected from the object, wherein the light originates from the light source.
