Abstract: The present invention provides a sensor combining a dust sensor and a gas sensor, comprising a light emitting unit for emitting light, a first light receiving unit for receiving scattered light which is emitted by the light emitting unit and scattered by dust to detect dust concentration, a mirror for changing a path of the emitted light which the light emitting unit emits, and a second light receiving unit for receiving the emitted light the path of which is changed by the mirror to detect gas concentration. An inflow section for introducing air into a detection space inside the sensor is formed in a Y-shaped tube in which a first inlet and a second inlet meet. The inflow section comprises a switch which selects a path through which air flows into the detection space out of the first inlet and the second inlet.

Abstract: A non-invasive measurement of biological tissue reveals information about the function of that tissue. Polarized light is directed onto the tissue, stimulating the emission of fluorescence, due to one or more endogenous fluorophors in the tissue. Fluorescence anisotropy is then calculated. Such measurements of fluorescence anisotropy are then used to assess the functional status of the tissue, and to identify the existence and severity of disease states. Such assessment can be made by comparing a fluorescence anisotropy profile with a known profile of a control.

Abstract: A method and system are presented for use in measuring on patterned samples, aimed at determining asymmetry in the pattern. A set of at least first and second measurements on a patterned region of a sample is performed, where each of the measurements comprises: directing illuminating light onto the patterned region along an illumination channel and collecting light reflected from the illuminated region propagating along a collection channel to be detected, such that detected light from the same patterned region has different polarization states which are different from polarization of the illuminating light, and generating a measured data piece indicative of the light detected in the measurement. Thus, at least first and second measured data pieces are generated for the at least first and second measurements on the same patterned region. The at least first and second measured data pieces are analyzed and output data is generated being indicative of a condition of asymmetry in the patterned region.

Abstract: In the present invention, cells cultured inside the wells of a microplate are observed easily and clearly regardless of the height or curvature state of the liquid surface of the culturing liquid. Provided is an observation device that includes an illumination optical system that irradiates a transparent sample with illumination light from a light source, an objective lens that collects observation light from the sample, a detection optical system that detects the observation light collected by the objective lens, and a retroreflective member that is arranged opposite the objective lens with the sample interposed therebetween and in which a plurality of very small reflective elements are arrayed. The objective lens and the illumination optical system are arranged below the sample in the direction of gravity.

Abstract: A method of measuring Raman scattering includes exciting Raman scattering of a sample with a first wavelength and a second wavelength of electromagnetic radiation traveling along a common optical path to form a first scattered radiation and a second scattered radiation. The first wavelength reaches the sample polarized in a first direction, and the second wavelength reaches the sample polarized in a second direction perpendicular to the first direction. The method includes collecting a first Raman spectrum from the first scattered radiation, collecting a second Raman spectrum from the second scattered radiation, and forming a decomposed Raman spectrum based on the first Raman spectrum and the second Raman spectrum. The decomposed Raman spectrum may be substantially free of noise, such as fluorescence and background radiation. Related spectrometers and laser devices are disclosed.

Abstract: A measuring apparatus is provided for inspecting a seal of an item. The measuring apparatus includes a radiation source for providing radiation for illuminating the seal of the item, a detector for receiving radiation from the item for generating a corresponding detected signal, and a processing arrangement for processing the detected signal to generate an output signal indicative of a state of the seal. The radiation source is arranged to focus the radiation into a plurality of focal points at the seal of the item, wherein the focal points are mutually spatially spaced apart. Moreover, the detector is arranged to image one or more of the focal points and to be selectively sensitive to an intensity of radiation received from the one or more focal points to generate a detected signal.

Abstract: The invention relates to a method for investigating a sample, the sample being impinged upon by illuminating light, and detected light emerging from the sample being directed to a detector, and the illuminating light being directed through an acousto-optic component with which the impingement upon the sample by illuminating light can be temporarily interrupted. The method is notable for the fact that the sample is illuminated with a first illuminating light bundle that has a first linear polarization direction, and with a second illuminating light bundle whose linear polarization direction is continuously switched over between the first linear polarization direction and a second linear polarization direction different from the first linear polarization direction, the illuminating light having the first linear polarization direction proceeding along a first light path and illuminating light having the second linear polarization direction proceeding along a second light path, and the acousto-optic component combining the light paths.
