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.

摘要： A measuring endoscope for making three-dimensional measurements of a object without using a special lattice and without hampering direct observation of the object. The measuring endoscope includes a light supply source for supplying illumination, and an illumination variation device for providing a plurality of particular illuminations, and illumination transmission means including a plurality of fiber optic cables. The fiber optic cables have a first input section separated from a second input section. The second section receives one particular illumination which the first section does not. At the output end of the fiber optic cables, fiber optic cables from the first section are interlaced, row-by-row with the fiber optic cables from the second section. An illumination lens then directs the light from the fiber optic cables onto the object. A lattice-shaped light pattern then appears on the object. Light reflected from the object is received by an objective lens system and is directed to an imaged sensor. The image sensor includes a large number of regularly arranged picture elements. Image processing devices then convert the received image into electrical signals. The image processing means process selected electrical signals from among all electrical signals received. These selected electrical signals are obtained from picture elements from positions where the lattice of the object image is formed on the light receiving surface. These selected electrical signals may then be processed to provide a three-dimensional measurement of the object. A control device controls the supply of light to the fiber optic cables to ensure that the light is emitted from the fiber optic cables in a lattice form. Finally, a display device connected to the image processor provides a display according to the three-dimensional image of the object.
