    Abstract: The present disclosure provides an easily-miniaturized, conveniently-operated device for measuring a polarization degree and a refractive index of an object simultaneously under an identical measurement condition. The device includes a sample chamber (1) configured to receive the object, a polarization degree measuring member (2) configured to measure the polarization degree of the object received in the sample chamber (1), and a refractive index measuring member (3) configured to measure information corresponding to the refractive index of the object received in the sample chamber (1). The polarization degree measuring member (2) includes a polarization modulation member (11) configured to perform polarization modulation on a light beam (9) for analyzing the object and allow the modulated light beam to enter the sample chamber (1), an intensity detection member (12) configured to detect an intensity of the light beam (5) exiting from the sample chamber, and a polarization degree calculation member (13). The refractive index measuring member (3) includes a position detection member (26) configured to detect position information about a light beam (24) entering a prism (8) that forms a bottom of the sample chamber (1), and a refractive index (concentration) calculation member (13).

    Abstract: A gas analyser and detector has an infra red source, a gas chamber and a detector cell; the detector cell has a gas sample inlet, inlet and exit paths for an infra red beam and reflector means in the chamber comprising a convex surface and a concave surface. The reflector means ensures a long path length for the beam whilst reducing beam divergence and signal loss.

    Abstract: Apparatus and method for optically measuring concentrations of components are disclosed, which allow enhancement in measurement accuracy of concentration. The apparatus comprises a cell (1), a light irradiator (2), a photodetector (3), and an arithmetic unit (4). The cell (1), which is formed of a transparent member into a triangular shape in its cross section, has different optical path lengths and is to contain a sample (11) therein. The light irradiator (2), which comprises a variable-wavelength laser generator (12), and a measuring system (15) composed of convex lenses (13), (14), makes a laser beam from the variable-wavelength laser generator (12) enlarged in cross-sectional area greater than original and formed into collimated light, and makes the laser beam incident upon the cell (1). The photodetector (3) comprises a multiplicity of CCDs (16) arranged in parallel to the surface of the cell (1), so that it can detect intensity of rays of transmitted light that have traveled over different optical path lengths at positions of an equal distance from the cell (1). The arithmetic unit (4), receiving a signal from the individual CCDs 16, calculates concentrations of components in the sample (11) based on optimum optical path lengths for different wavelengths and values of transmitted light at positions of the optimum optical path lengths, and further outputs calculation results.

    Abstract: The present invention describes a low-cost, portable multi-parameter, turbidity sensor based on optical fiber.
    The sensor quantifies the transmission and scattering of radiation (nephelometry) in a fluid through radiation emission in two or more wavelengths. The invention can be used to estimate concentration of suspended sediments, to distinguish the type of sediment based on color, to distinguish different particle-size classes, and to identify and determine the concentrations of different suspended-sediment fractions.
    The sensor comprises the following elements: a radiation emitter of two or more wavelengths (2), a radiation receiver to measure the transmitted radiation (2), a radiation receiver to measure the scattered radiation (3), and an inner space (4) of the measurement unit containing the fluid being evaluated. The first three elements are located at the specified distances L1, L2 and L3, and at specified angles A1 and A2, as shown in the Figure
