    摘要: An image fiber includes plural kinds of cores and a common cladding containing the cores, which are arrayed so that no similar cores are adjacent one another. A method of making the image fiber is that a plurality of optical fiber elements having cores of different diameters are arranged so that no similar cores are adjacent one another, and after being inserted in a jacket pipe, are heated at a high temperature to fuse the cladding portions of the optical fiber elements so that the whole is drawn down to a desired thickness.

    摘要: An image fiber has a plurality of optical fibers with normalized frequencies different from one another, which is constructed so that a plurality of cores different in size and shape from one another are distributed at random in a cladding. The optical fibers include at least two kinds of optical fibers having propagation modes different in number. Thus, the image fiber is capable of suppressing cross talk to prevent the degradation of image quality.

    摘要: An imaging apparatus is provided with a negative lens, a variable focal length lens unit including a material with an electrooptic effect, a light blocking unit, including the material with the electrooptic effect, capable of changing an aperture diameter, and a switch, interlocked with each other, capable of supplying electric power to the variable focal length lens unit and the light blocking unit which are arranged in order on an optical axis from an object side to an image side. When the switch is turned off, the variable focal length lens unit is set to bring an object at a far point into focus and the light blocking unit is set so that an aperture is determined by an aperture stop, while on the other hand, when the switch is turned on, the variable focal length lens unit is set so that an object at a near point is in focus and the light blocking unit is set to be smaller in aperture. Apertures different in size are determined by a plurality of annular transparent electrodes incorporated in the light blocking unit and configured concentrically. Thus the imaging apparatus can be constructed to be small or compact in size and is easy in manufacturing.

Apertures different in size are determined by a plurality of annular transparent electrodes incorporated in the light blocking unit and configured concentrically.

    摘要: An image fiber is provided with an image transmitting portion including a plurality of cores and a cladding surrounding the cores; a jacket layer higher in refractive index than the cladding, covering the periphery of the image transmitting portion; and a coating layer higher in refractive index than the cladding, covering the periphery of the jacket layer. The image fiber, integrally constructed in this way, allows light propagating through the cladding to be effectively eliminated, and thus fails to produce flare.

    摘要: A TV system for endoscopes is configured to connect to a fiber scope using an image guide fiber bundle and a rigid endoscope using a relay lens system. An image is formed by either the fiber scope or the rigid endoscope on a TV monitor. The camera control unit controls a level of the color difference signal in accordance with spatial frequency components contained in the TV signal. A variable switching unit is provided which allows the electrical circuits of the camera control unit to function selectively in accordance with the characteristics of the image transmission system.
