Abstract: A microscope device includes an opening (31) that includes a first slit and a second slit through which a plurality of pieces of light from an observation target resulting from a plurality of pieces of irradiation light emitted to the observation target and having different wavelengths pass, a dispersion element that wavelength-disperses the plurality of pieces of light passing through the opening (31), and an imaging element (32) that receives the plurality of pieces of light wavelength-dispersed by the dispersion element. The imaging element (32) performs light reception so that, as for the plurality of pieces of light wavelength-dispersed, zeroth-order light of light passing through the second slit and first-order light of light passing through the first slit do not overlap with each other.

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: The present disclosure relates to limitation of noise on light detectors using an aperture. One example embodiment includes a system. The system includes a lens disposed relative to a scene and configured to focus light from the scene onto a focal plane. The system also includes an aperture defined within an opaque material disposed at the focal plane of the lens. The aperture has a cross-sectional area. In addition, the system includes an array of light detectors disposed on a side of the focal plane opposite the lens and configured to intercept and detect diverging light focused by the lens and transmitted through the aperture. A cross-sectional area of the array of light detectors that intercepts the diverging light is greater than the cross-sectional area of the aperture.

Abstract: The present invention relates to a color control system for controlling, in real time, the color of an article positioned on a moving carrier. The system comprises: an illuminating device configured to illuminate said moving article in successive illuminating cycles, each illuminating cycle comprising successively generating, at a given rate, a given number of lines of light having distinct spectral bands said lines of light being substantially perpendicular to the direction of movement; a detecting device configured to detect the light backscattered by the article successively illuminated by each of said lines of light, such as to generate for each dot of a given number of dots of an observation strip perpendicular to the direction of movement, a number of signals corresponding to the light backscattered by said dot; and a processing unit configured to determine at least one value representative of the color of said dot.

Abstract: A label-free optical device for near real time quantification of the multifractal micro-optical properties of a sample includes a source of broadband light; a tunable filter that receives at least a portion of the broadband light and then transmits narrowband light, whereby a specific band of light is selected to avoid unwanted absorption of light by the sample; where the narrowband light is configured to illuminate a selected area of the sample, and in response elastically-scattered light is dispersed from the sample; a light collection device configured to collect at least some of the elastically-scattered light; where at least some of the collected elastically-scattered light is configured to be transmitted to a detector by the light collection device, and the detector is configured to record a light scattering signal; and where the detector is configured to perform light scattering signal measurements at multiple angles or wavelengths to determine a refractive index multifractality of the sample.

Abstract: Aspects relate to mechanisms for mass screening of samples. A portable laboratory device based on spectroscopic analysis of samples containing analytes under test can facilitate the mass screening. The portable laboratory device can include a sample head including a structure configured to facilitate application of the sample to the sample head and an optical measurement device including one or more light sources and a spectrometer. Light from the light source(s) incident on the sample may be directed to the spectrometer to obtain a spectrum of the sample. The optical measurement device can further include a data transfer device configured to provide the spectrum obtained by the spectrometer to a spectrum analyzer to produce a result from the spectrum.

Abstract: A system for measuring the spatial distribution of the spectral emission of a measurement zone of an object, comprises: a first objective; means for selecting a portion of an image formed by the first objective; a diaphragm; light-dispersing means located in the vicinity of the diaphragm and allowing the light coming from the selecting means to be dispersed; and a second objective placed between the selecting means and the diaphragm, interacting with the first objective so that the aperture of the diaphragm is optically conjugated with the measurement zone by the first and second objectives. The first objective forms an image on a predetermined Fourier surface on which each point corresponds to an emission direction of the object for one particular wavelength. The selecting means have a selection surface shaped depending on the predetermined. Fourier surface, and the selecting means are placed on the predetermined Fourier surface.
