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 imaging apparatus is provided with a negative lens, a variable focussing 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 focussing 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 focussing 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 swtich is turned on, the variable focussing 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.
