    摘要： A fiber optic structure (571) comprising an optical fiber (52) having a body of metallic material (561) deposited upon the exterior surface such that the body of material is sufficiently strong and rigid to permit processing of the fiber for various fiber optics applications. The metallic body has a face (58,60) and the optical fiber extends the the face. The face is disposed at an angle to enhance internal reflection of light in the fiber directed towards the face. In this way, liquid level sensors and other types of mode strippers and temperature sensors are formed. The process for forming the fiber optic structure involves the electroplating of a body of material upon the exterior surface of the optical fiber which is to be processed.

    摘要： An automatic refractometer comprising a photosensitive device having a relatively narrow dynamic range in the form of a linear scanned array including a plurality of photoelectric elements each providing an output pulse during a scan and the amplitude of each pulse being determined by the amount of illumination of the corresponding element by incident light, an optical system for directing light onto the array in a manner such that the particular photoelectric elements of the array which are illuminated by the light are determined by the index of refraction of a light transmitting substance placed in operative association with the optical system, a circuit for converting signals from the array into digital signals containing information as to the amplitudes of the signals from the array, a digital processing circuit for storing respective signals from reference and sample substances placed in operative association with the optical system and for computing the index of refraction of the sample substance by means of a comparison of the stored reference and sample information, and apparatus for providing a read out of the computed result. The digital processing circuit also calculates the percent solids in the sample substance, and the circuit also includes a plurality of channels for containing information to provide different interpretations of the index of refraction computed thereby. The circuit for converting array signals into digital signals comprises a peak detector circuit for detecting peak amplitudes of signals obtained from scanning the array and an analog-to-digital converter for providing digital signals containing information as to peak amplitudes of the array signals. There is also provided arrangements for measuring the temperatures of the sample substance and comparing to a reference for applying a temperature correction to the computed index of refraction, monitoring and regulating the temperature of the component of the optical system to which the sample substance is exposed, and monitoring and regulating the intensity of light incident on the array.

    摘要： Réfractomètre destiné à la mesure de l'indice de réfraction d'un milieu 2, utilisant la méthode de l'angle limite.
    Une source 4 éclaire une fente-source 5 qui a pour image par rapport à un système optique S l'une des fentes 5' d'une grille fixe 6 perpendiculaire à l'axe optique et percée de fentes 5' parallèles entre elles régulièrement espacées correspondant chacune à une angle d'incidence du faisceau optique sur le prisme 3. Des moyens 7 sont prévus pour que l'image 5' de la fente-source 5 sur la grille 6 puisse être successivement chacune des fentes 5' et la grille 6. La pupille, L 1 , située dans le plan de la source, est conjuguée avec la face 8 de sortie du prisme 3 et reste immobile lors du déplacement de l'image 5' de la fente-source 5 sur la grille 6.
    Application à la mesure de l'indice de réfraction d'un milieu, en particulier d'un milieu liquide.

    摘要： A refractometer (20) includes an enclosure (40), a single use prism (30), a light source (50), and an index of refraction (IoR) sensor (55). The single use prism is removably disposed within the enclosure. The light source and IoR sensor are disposed within the housing and are configured to be repeatably used with a series of single use prisms of similar construction. One single use prism can be removed after being used, and a new single use prism can be installed in the enclosure for use with the same light source and IoR sensor as were used with the first prism.
