Abstract: Apparatus and methods are described for use with feces of a subject that are disposed within a toilet bowl, and an output device. One or more light sensors are configured to receive light from the toilet bowl, while the feces are disposed within the toilet bowl. A computer processor analyzes the received light, and, in response thereto, detects a currently-occurring inflammatory bowel disease episode, and/or a predicted upcoming inflammatory bowel disease episode. The computer processor generates an output on the output device, at least partially in response thereto. Other applications are also described.

Abstract: A quantum absorption spectroscopy system (100) includes a laser light source (1), a quantum optical system (201), a photodetector (31), and a controller (4). The laser light source (1) emits pump light. The quantum optical system (201) includes a nonlinear optical crystal (23) that generates a quantum entangled photon pair of a signal photon and an idler photon by irradiation with pump light, and a moving mirror (25) that changes a phase of the idler photon, and causes quantum interference between a plurality of physical processes in which the quantum entangled photon pair is generated. The photodetector (31) detects the signal photon when the phase of the idler photon is changed by the nonlinear optical crystal (23) in a state where a sample is disposed on an optical path of the idler photon, and outputs a quantum interference signal corresponding to the detected number of photons. The controller (4) calculates an absorption spectroscopy characteristic of the sample by performing Fourier transform on the quantum interference signal.

Abstract: A spectroscopic assembly may include a spectrometer. The spectrometer may include an illumination source to generate a light to illuminate a sample. The spectrometer may include a sensor to obtain a spectroscopic measurement based on light, reflected by the sample, from the light illuminating the sample. The spectroscopic assembly may include a light pipe to transfer the light reflected from the sample. The light pipe may include a first opening to receive the spectrometer. The light pipe may include a second opening to receive the sample, such that the sample is enclosed by the light pipe and a base surface when the sample is received at the second opening. The light pipe may be associated with aligning the illumination source and the sensor with the sample.

Abstract: A system includes a processor receiving spectrometer data representative of a scanned sample and generated by a spectrometer and a cloud server including a server processor. The server processor receives the spectrometer data generated by the spectrometer from the processor, analyzes the spectrometer data, identifies, based on a machine learning application, one or more unique characteristics of the spectrometer data which uniquely identifies the scanned sample and provides to the processor data representative of a graphical display, which includes an indication of whether or not the scanned sample includes the one or more unique characteristics of the spectrometer data.

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 spectroscopic analyzer includes: an irradiator that irradiates a target measurement object with lights of a plurality of different wavelengths sequentially as a pre-irradiation, and, after the pre-irradiation, further irradiates the target measurement object with lights of a plurality of different wavelengths sequentially as a measurement-irradiation; a detector that, during the measurement-irradiation, detects reflected light, transmitted light, or a transmitted reflected light from the target measurement object at each of the plurality of different wavelengths of the measurement-irradiation and that outputs absorbance spectral data; a data analyzer that analyzes the absorbance spectral data; and a result display that displays analysis results related to components of the target measurement object.

Abstract: The invention comprises a method and apparatus for selecting optical pathways sampling a common tissue layer, such as the dermis, of a person for analysis in a noninvasive analyte property determination systemy, comprising the steps of: probing skin with a range of illumination zone-to-detection zone distances with at least two wavelength ranges, which optionally overlap, and selecting, using a metric, illumination zone-to-detection zone distances having mean optical pathways probing the common tissue layer, such as without the mean optical pathways entering the subcutaneous fat layer of the person. Optionally, the skin tissue layers are modulated and/or treated via tissue displacement before and/or during data collection.

Abstract: Wearable spectroscopy systems and methods for identifying one or more characteristics of a target object are described. Spectroscopy systems may include a light source configured to emit light in an irradiated field of view and an electromagnetic radiation detector configured to receive reflected light from a target object irradiated by the light source. One or more processors of the systems may identify a characteristic of the target object based on a determined level of light absorption by the target object. Some systems and methods may include one or more corrections for scattered and/or ambient light such as applying an ambient light correction, passing the reflected light through an anti-scatter grid, or using a time-dependent variation in the emitted light.

Abstract: A spectrophotometer includes: an infrared light source; an interferometer; a first detector; and a monitor unit. The monitor unit includes: a second detector; and a light amount control unit. The light amount control unit is operable to control the infrared light source such that the amount comes closer to a target light amount, based on the signal. The infrared light source emits light having a first wavelength range and light having a second wavelength range different from the first wavelength range. The second detector includes: a first light detection element; and a second light detection element. The first light detection element outputs to the light amount control unit a first voltage corresponding to the light having the first wavelength range. The second light detection element outputs to the light amount control unit a second voltage corresponding to the light having the second wavelength range.
