    摘要： An optical apparatus includes an optical element that is made of a medium exhibiting negative refraction. A correction varies a wavelength of light used, thereby correcting a variation in image forming capability, which occurs due to one of a variation in refractive index of the optical element and a variation in refractive index of a surrounding medium.

    摘要： A focal-length adjusting unit for photographing apparatuses includes a distance-measuring means for detecting the amount of defocus to an object by using a light beam of the object passing through a photographing optical system; at least two optical elements located in an optical path for distance measurement, deflecting incident light from the object to introduce the light into an image sensor or a distance-measuring sensor; a variable optical-property element constituting at least one of the optical elements, capable of changing the deflection of light in accordance with an applied voltage or an applied current; and a voltage applying means or a current applying means for applying a voltage or a current in accordance with the distance-measuring output of the distance-measuring means. In this case, before a distance measurement is made by the distance-measuring means, the function of light deflection of the variable optical-property element is set to a predetermined value.

    摘要： The invention provides an optical apparatus enabling diopter adjustment, etc. to be achieved using, for instance, a reflection type variable-optical property optical element or a variable-optical property mirror but without recourse to any mechanical moving part. The variable-optical property mirror 9 comprises an aluminum-coated thin film 9a and a plurality of electrodes 9b. Via variable resistors 11 and a power source switch 13 a power source 12 is connected between the thin film 9a and the electrodes 9b, so that the resistance values of the variable resistors 11 can be controlled by an operating unit 14. The shape of the thin film 9a as a reflecting surface is controlled by changing the resistance value of each variable resistor 11 in response to a signal from the operating unit 14 in such a manner that the imaging capability of the variable mirror is optimized.

    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.
