摘要： In order to enhance resolving power and making the fabrication of an optical system easy, the image pickup device is of an arrangement that a color-separating optical means is disposed between an objective lens and a solid-state image sensor, and those images by the respective color lights which are focused at mutually displaced positions on the solid-state image sensor are integrated into one unified image by a signal processing circuitry to thereby collect also the image-informations corresponding to those areas lying between the picture elements. The color-separating optical means may be formed by either one of a color dispersion prism, a dichroic mirror, a diffraction grating, a glass block made of a medium of heterogeneous material and a light-divider containing liquid crystal.

摘要： An image pickup system with an illuminating device capable of sequentially irradiating three kinds of color lights different from each other onto an object, an objective lens system forming images of the object with the color lights, a solid-state image sensor receiving the images of the object, a signal processing device producing individual color images of the object based on electric signals supplied from the solid-state image sensor, and a color dispersion device or a color separation device disposed in an optical path of light incident on the solid-state image sensor from the object. The color dispersion device includes the combination of variously shaped prisms and a diffraction grating, and the color separation device includes a structure compounded of dichroic mirrors, whereby the images with respective color lights are incident at positions shifted each other on the solid-state image sensor. The compound of signals indicative of individual color images makes it possible to bring about the object image with high resolution.

In order to shorten total length and minimize outside diameter of the objective optical system and enable to sufficiently eliminate the infrared light incident from the object, the objective optical system comprises at least one optical component made of a substance absorbing the light having the oscillation frequency of the YAG laser light and interference films reflecting the light having the oscillation frequency of the YAG laser light formed on the cemented surfaces of the optical components and/or the surface of emergence of a rear group designed as a positive lens component.

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.

摘要： An optical system is disclosed for an endoscope having a generally tubular distal end in which an objective lens assembly and an image sensor in the form of a solid-state video camera are internally housed so that an image formed by the lens assembly is focussed upon the input or pickup surface of the video camera. The video camera is disposed along or in proximity to the center axis of the distal end of the endoscope and in some instances is oblique with respect to the center axis. The video camera may be positioned in this way due to the provision of a reflecting surface which is angularly disposed in opposing relationship with an input surface of the video camera, and deflection means disposed in front of the lens assembly and within the objective lens assembly, or between the lens assembly and the reflecting surface so that an image formed by the lens assembly can be focussed on the input surface of the video camera.
