    摘要： Disclosed is a glow discharge spectrometry device including a glow discharge lamp and an optical emission spectrometer adapted to receive a light beam emitted by a glow discharge plasma. The optical emission spectrometer includes a dispersive optical component and an echelle grating arranged and configured in such a way as to form a two-dimensional spectrum of the light beam, the two-dimensional spectrum being dispersed in a plurality of diffraction orders, the plurality of diffraction orders extending along a first direction and each diffraction order extending spectrally according to a second direction transverse to the first direction and a pixel-array CMOS sensor arranged and configured to acquire the two-dimensional spectrum as a function of time.

    摘要： A dispersion measurement apparatus includes a pulse forming unit, an imaging unit, and an operation unit. The pulse forming unit forms a light pulse train including a plurality of light pulses having time differences and center wavelengths different from each other from a light pulse output from a pulsed laser light source. The imaging unit includes an image sensor capable of performing imaging at an imaging interval shorter than a minimum peak interval of the light pulse train, and images a light pulse train passed through a measurement object to generate imaging data. The operation unit receives the imaging data, detects a temporal waveform of the light pulse train for each pixel of the image sensor, and estimates a wavelength dispersion amount of the measurement object for each pixel of the image sensor based on a feature value of the temporal waveform.

    摘要： An optical absorbance spectrometer including a sample housing configured to hold a sample, a light source configured to emit broadband light into the sample housing, one or more reflectors configured to reflect the light such that the light passes through a sample holding volume of the sample housing multiple times, and a sensor arranged to receive the light from the sample housing, after the reflections. The sensor comprises a plurality of detectors configured to detect the intensity of the received light at multiple different wavelengths.

    摘要： An illumination system for recognizing material includes a measurement stage, a light-providing part, a light-receiving part, and a processing part. The measurement stage is upwardly open and the measurement target is located on the measurement stage. The light-providing part includes a plurality of illumination sections providing incident lights to the measurement target, and provides multi-directional incident lights to the measurement target from multiple upper directions at which the measurement stage is open. The light-receiving part receives single-directional reflection lights reflected by the measurement target according to the multi-directional incident lights provided by the light-providing part. The processing part acquires a multi-directional intensity distribution of multi-directional reflection lights reflected by the measurement target according to a single-directional incident light from the single-directional reflection lights reflected by the measurement target according to the multi-directional incident lights, and determines material of the measurement target from the multi-directional intensity distribution of reflection lights. Thus, material of an object may be easily and accurately known at a low cost.
