    Abstract: An embodiment of a ruggedized interferometer is described that comprises a light source that generates a beam of light; a fixed mirror; a moving mirror that travels along a linear path; a beam splitter that directs a first portion of the beam of light to the fixed mirror and a second portion of the beam of light to the moving mirror, wherein the beam splitter recombines the first portion reflected from the fixed mirror and the second portion reflected from the moving mirror; and a servo control that applies a substantial degree of force to the moving mirror at initiation of a turnaround period, wherein the substantial degree of force is sufficient to redirect the moving mirror traveling at a high velocity to an opposite direction of travel on the linear path.

    Abstract: A spectroscopic analysis apparatus includes a laser light source that emits laser light, of which wavelength changes, toward a reflector inside a probe, the probe being configured to be disposed in a flow passage of a measurement target fluid, a light receiver that receives the laser light reflected by the reflector, and a controller that analyzes the measurement target fluid using a result of reception acquired by the light receiver and controlling the laser light source. The controller controls the laser light source to perform at least one scan of the laser light, the controller controlling the laser light source such that a scanning time of the laser light is equal to or shorter than a light-receivable time of the laser, the scanning time being a time to scan the laser light emitted from the laser light source in a certain wavelength range, the light-receivable time being a time in which the laser light reflected by the reflector can be received by the light receiver.

    Abstract: Aspects of blending data detected by a monochromator over multiple wavelength ranges is described herein. In one embodiment, the monochromator includes a diffraction grating, a grating drive motor that rotates the diffraction grating to provide, by diffraction of broadband light, first dispersed wavelengths of light and second dispersed wavelengths of light, a detector that detects a first reflection from the first dispersed wavelengths of light and a second reflection from the second dispersed wavelengths of light, and processing circuitry that blends data values from the first reflection and data values from the second reflection together to provide a spectrum of combined data values. By blending data detected over multiple ranges, measurements of relatively high precision and quality can be provided over a wider spectral range.

    Abstract: A portable complete analysis solution that integrates computer vision, spectrometry, and artificial intelligence for providing self-adaptive, real time information and recommendations for objects of interest. The solution has three major key components: (1) a camera enabled mobile device to capture an image of the object, followed by fast computer vision analysis for features and key elements extraction; (2) a portable wireless spectrometer to obtain spectral information of the object at areas of interest, followed by transmission of the data (data from all built in sensors) to the mobile device and the cloud; and (3) a sophisticated cloud based artificial intelligence model to encode the features from images and chemical information from spectral analysis to decode the object of interest. The complete solution provides fast, accurate, and real time analyses that allows users to obtain clear information about objects of interest as well as personalized recommendations based on the information.

    Abstract: A protective sheath having a closed end and an open end is sized to receive a hand held spectrometer. The spectrometer can be placed in the sheath to calibrate the spectrometer and to measure samples. In a calibration orientation, an optical head of the spectrometer can be oriented toward the closed end of the sheath where a calibration material is located. In a measurement orientation, the optical head of the spectrometer can be oriented toward the open end of the sheath in order to measure a sample. To change the orientation, the spectrometer can be removed from the sheath container and placed in the sheath container with the calibration orientation or the measurement orientation. Accessory container covers can be provided and placed on the open end of the sheath with samples placed therein in order to provide improved measurements.

    Abstract: A delay line device and a terahertz time-domain spectrometer system include: a baseplate, a slide rail component, in which the slide rail component includes a slide, a reflector, a grating ruler component, and an electric-magnetic induction component. When the electric-magnetic component, after being applied a current, cuts the magnetic induction coil to generate power to push the slide moving, the grating ruler component placed on the slide rail component collects the movement information of the slide. The slide's movement drives the reflector placed on the slide to move together to change the optical distance of a pump light, so as to generate the delay between the pump light and a probe light.The changes to the abstract are shown below:A delay line device and a terahertz time-domain spectrometer system include: a baseplate, a slide rail component, in which the slide rail component includes a slide, a reflector, a grating ruler component, and an electric-magnetic induction component.
