    摘要： A high-resolution sensor of magnetic field sensor system and materials for use in such a system are described. The sensor systems measure a magnetic field using inorganic and/or organic magneto-optically active materials, e.g. polymer material and have an interferometer based on Faraday rotation. The polymer material is preferably in the form of a film. The polymer material has an optical property that is sensitive to the magnetic field, e.g. the Faraday rotation effect. The present invention also provides a sensor head structure comprising the above polymer material. The sensor head may be designed for use with an optical fiber or with mirrors. In particular the present invention provides a fiber Sagnac interferometer to measure the rotation of polarized plane of light. The present invention provides a fiber or mirror based Sagnac interferometer with passive phase bias applied to magnetic field sensing. This invention has the following three major aspects each being an embodiment of the present invention: 1. Sensing material: a conjugate polymer such as polythiophene and/or a polymer containing superparamagnetic nanoparticles that exhibits a giant Faraday rotation. 2. Magnetic field probe that incorporates the above polymer or polymer/nanoparticle composite, e.g. in the form of a film. 3. Sensor: The sensor combines an optical fiber-based Sagnac interferometer and the above magnetic field probe.

    摘要： A zoom lens barrel includes a stationary cylindrical member, a rotatable cam ring and a linearly-guided member concentrically provided in that order from the outside of the zoom lens barrel, a first cam mechanism which is provided between the rotatable cam ring and the linearly-guided member to move the linearly-guided member in an optical axis direction without rotating upon rotation of the rotatable cam ring, and a second cam mechanism provided between the stationary cylindrical member and the rotatable cam ring to move the rotatable cam ring in an optical axis direction upon rotation of the rotatable cam ring. The second cam mechanism causes the rotatable cam ring to rotate while moving in the optical axis direction so that the amount of movement of the rotatable cam ring in the optical axis direction with respect to the angle of rotation thereof is nonlinear.

    摘要： A structure (113b) which includes an overhang and a support portion supporting substantially the center of the overhang, and in which the area of the support portion is smaller than the area of the overhang in the two-dimensional direction of an upper electrode (110b) is formed on the upper electrode (110a) in a region above each lower electrode 105a in one-to-one correspondence with the lower electrode (105a). An object of surface shape sensing, e.g., the tip of a finger (1602) touches the surface of the overhang of the structure (113b), and the support portion of the structure (113b) whose overhang is in contact with the object of sensing pushes down a portion of the upper electrode (110a) toward the lower electrode (105a), thereby deforming the upper electrode (110a).
