摘要： In the field of lighting devices comprising two fiber sources of light and a light transport comprising a plurality of second multimode optical fibers, such devices are designed to be installed in intra-operative optical probes requiring a perfectly uniform visible illumination and fluorescence illumination. A lighting device is provided which comprises a single lens disposed between the fiber sources and the input of the light transport and an optical diffuser. A lighting device is also provided which comprises an afocal system disposed between the fiber sources and the input of the light transport and an optical diffuser. An optical fiber coupler or a semi-reflecting plate provides the mixing of the two fiber sources.

摘要： Photoacoustic detecting device (1), intended to be applied, via a contact face (3), against a medium to be analysed, the device comprising:
a hollow cavity (20) comprising a first aperture (22) produced in the contact face, the cavity being bounded by a containment shell (21) that extends around the first aperture;
a pulsed or amplitude-modulated light source (10) configured to emit, in an emission spectral band (Δλ), an incident light wave (11) through the cavity (20) to the first aperture;
an acoustic transducer (28) linked to the cavity and configured to detect a photoacoustic wave (12) extending through the cavity.
The photoacoustic detecting device is optimized to increase the amplitude of the photoacoustic wave detected by the acoustic transducer.-

摘要： A device for observing a biological sample is provided, including: a light source to emit a light beam at a wavelength between 1 μm and 20 μm; an image sensor including pixels defining a detection plane; a holder to hold the sample between the source and the sensor at a distance from the plane smaller than 1 mm, such that the source is configured to illuminate an area of the sample larger than 1 mm2, no image-forming optics are placed between the sample and the sensor, and the sensor is configured to acquire an image corresponding to an area of the sample larger than 1 mm2 and representative of an absorption of the beam by the sample at the wavelength; and a processor to determine a map of an amount of analyte in the sample, based on the image acquired by the sensor, the analyte absorbing light at the wavelength.

摘要： The invention relates to a method for quantifying the level of agglutination of particles in a sample, in particular a biological sample, and notably blood. The biological sample is positioned between a light source and a matrix photodetector. The image acquired by the photodetector is representative of the level of agglutination of the particles in the sample. The light source emits a light wave, the spectral band of which extends an optimum 400 and 600 nm, which constitutes an optimum an excessively low absorption and excessively high absorption, given the thickness of the sample.

摘要： The invention is a method for estimating the amount of analyte in a fluid sample, and in particular in a bodily fluid. The sample is mixed with a reagent able to form a color indicator in the presence of the analyte. The sample is then illuminated by a light beam produced by a light source; an image sensor forms an image of the beam transmitted by the sample, from which image a concentration of the analyte in the fluid is estimated. The method is intended to be implemented in compact analyzing systems. One targeted application is the determination of the glucose concentration in blood.
