    摘要： In a recording apparatus for reproducing information recorded on a recording medium by utilizing near-field light, the recording apparatus realizes reliable information reproduction with a simple structure. Illumination light 20 is illuminated to the recording medium 10 to create near-field light on a surface of the recording medium 10. The created near-field light is scattered by a microscopic aperture 12 formed in the aperture element 11 so that scattering light (propagation light) thereof is detected to create a reproduced signal. Derived from the created reproduced light a distance control signal representative of a distance between the microscopic aperture 12 and the recording medium 10. Based on the distance control signal, the aperture element 11 is controlled in position. Due to this, the microscopic aperture 12 is brought into proximity to the recording medium 10.

    摘要： A near-field optical head has a tip end having an edge portion defined by two intersecting planes. Information recorded on a recording medium is reproduced in accordance with an intensity of scattered light of an evanescent field generated when the recording medium is illuminated with light and the tip end of the optical head is brought proximate the recording medium at an interval equal to or smaller than a wavelength of light therebetween.

    摘要： A single lens reflex camera is provided with a photocell so positioned in the camera as to receive thereon light incident through the lens and reflected onto the photocell by the mirror. During each photographing operation, the mirror is pivotally elevated so that the incident light is no longer received by the photocell. The camera electronics monitors the photocell output which is representative of the magnitude of light received by the photocell and, unless a relatively rapid change in photocell output is detected during a photographing operation, an alarm is actuated to indicate failure of the mirror to properly pivot.

    摘要： A simplified field emission type light-to-current converter having a high sensitivity and high-speed response (on the order of picoseconds) which obtains a large field emission current comprises an optical pumping field emission type light-to-current converter. In one embodiment, the optical pumping field emission type light-to-current converter includes an optical waveguide through which light may be propagated, a conductive transparent film, one of a semiconductor material and an insulating material, and a conductor. The waveguide, conductive transparent film, and insulator or semiconductor are joined to each other such that when light is projected through the waveguide and a bias voltage is applied across the conductive transparent film and the conductor, a field emission current is obtained. A light emission side of the optical wave guide material is in contact with the transparent conductive film and may be provided with a sharpened end portion or a plurality of needle-like projections formed therein.
