    Abstract: An optical system having a first order spectral range that is usable in an optical spectrum analyzer receives an broadband optical test signal and a optical calibration signal and couples the optical signals via two optically isolated paths to separate optical detectors. First and second pairs of optical fibers, with each pair having an input fiber and an output fiber, are positioned in a focal plane of a collimating optic that has an optical axis. The fiber pairs are symmetrically positioned on either side of the optical axis with the input fibers positioned on one side of the optical axis and the output fibers positioned on the opposite side of the optical axis. The input fibers receive the optical test signal and the optical calibration signal. The output optical fibers are coupled to first and second optical detectors. An optical calibration source generates second order or greater spectral lines that fall within the first order spectral range of the optical system. A diffraction grating receives the optical test signal and the optical calibration signal from the collimating optic and separates the first order spectral components of the broadband optical test signal and passes the second order or greater spectral lines of the optical calibration signal. The first optical detector that is responsive to the first order spectral components of the optical test signal receives the optical test signal from the collimating optic and converts the optical test signal to an electrical signal. A second optical detector that is responsive to the second order or greater spectral lines of the optical calibration signal concurrently receives the optical calibration signal from the collimating optic and converts the calibrations signal to an electrical signal.

    Abstract: The present invention pertains to a miniaturized optical component consisting of at least two elements (10, 30), of which at least one (10, 30) has optical microstructures (52, 53, 54). The components (10, 30) are separated by one ore more distance cast pieces (20). The components (10, 30) and the distance cast piece (20) have self-adjustable elements (40) for ensuring a precise relative adjustment when assembling such elements and the distance cast piece. The aim of the invention, which consists in facilitating assembly, can be reached as follows: the two elements are interconnected by means of attaching fittings to form one piece. Fibre tape or a foil-type hinge can be used as an attaching fitting (60-63). According to the inventive production process, the components and the distance cast piece are manufactured in one step together with their self-adjustable elements by a moulding technique, whereby two components are made at the same time to form one piece by means of an attaching fitting.

    Abstract: A high resolution fast imaging spectrograph is disclosed which provides 400 spatial channels and 100 spectral channels of information. A collimating mirror (10) and a focusing mirror (12) face a plane diffraction grating (14), which is positioned at an acute angle to the perpendicular to the optic axis. An elongated slot (16) is cut through approximately the center of the grating allowing the light source (18) to pass through the slot and onto the collimating mirror. A turning mirror (20), which is placed at the focus of the focusing mirror and adjacent to the slot, directs radiation to a camera mirror (22), which focuses a final image outside the instrument enclosure onto a detector (24). The light source to the instrument is provided by an optical fiber ribbon. The detector will commonly be a CCD or CID 2-D detector, permitting the simultaneous measurement of spectral distribution of a spatial profile. The instrument requires no power input, has no moving parts, and is completely passive with no operating controls or adjustments. Also disclosed is a commercially significant means to utilize the high spatial resolution imaging spectrograph in earth science remote imaging applications through the utilization of a reflecting telescope connected to the spectrograph by means of an optical fiber ribbon.

    Abstract: Une commande améliorée de balayage d'un miroir permettant d'entraîner un miroir mobile (14) dans un interféromètre avec une vitesse de balayage constante comprend une servo-commande à boucle fermée permettant d'obtenir un balayage du miroir à vitesse constante en réponse à une comparaison de phases d'un signal dérivé de la fréquence de battement d'un rayon laser à deux fréquences (16) traversant l'interféromètre et d'un signal de référence à une fréquence sélectionnée, la différence entre les fréquences ou la fréquence de battement du rayon laser à deux fréquences étant stabilisée à une valeur prédéterminée de différence entre les fréquences. La commande de balayage de miroir utilise une boucle de commande à verrouillage de phase qui verrouille la fréquence du signal de référence par rapport à la fréquence du signal dérivé du rayon laser, afin de permettre une commande précise de la vitesse du miroir.

    Abstract: A scanning microscope includes a scanning unit that causes irradiation light emitted by a light source to scan a sample, an optical system that guides the emitted light that has passed through the scanning unit to the sample, an isolation unit that includes a transmissive portion that enables the irradiation light to pass the transmissive portion and a reflective portion that reflects at least some of light that is included in emitted light generated from the sample as a result of the irradiation light being radiated to the sample and that has passed through the optical system and the scanning unit, and a detection unit that detects the emitted light that has passed through the isolation unit. The isolation unit is disposed in an optical path of the irradiation light between the light source and the scanning unit.

    Abstract: A fiber optic probe assembly is provided. The probe comprises a first optical system and a second optical system, a delivery light guide comprising one or more than one delivery optical fiber for transmitting excitation radiation from a radiation source disposed at a proximal end of the light guide to the first optical system. The first optical system comprising one or more than one first optical element for forming a substantially collimated illumination beam from the excitation radiation. An optically opaque tubular sleeve is fitted over the first optical system to optically isolate the first optical system and the delivery light guide from the second optical system. The second optical system comprising one or more than one second optical element for gathering optical radiation scattered from a sample and forming the optical radiation into a collection beam. A collection light guide comprising one or more than one collection optical fiber receives the collection beam and transmits the collection beam to an analyzer. The first and second optical systems are disposed within a housing so that an emission cone of the first optical system and an acceptance cone of the second optical system substantially overlap. A spectroscopic measurement system comprising the optic fiber probe is also provided.
