    • The axial position of the fiber is controlled in three grinding or polishing stages. The fiber (72) is first ground flush with the guide (120) in which it is housed. The fiber end and face of the guide are then ground flat and square. The fiber is thereafter polished to its optical quality and required length. The tool for accomplishing these steps includes a retainer (74) which holds the fiber optic ferrule (70) and its optical fiber (72) therein at a tool surface (16). This tool surface is protected by a guard (18) from being too rapidly ground away while the fiber and fiber/guide combination are ground flush with the surface. The surface and its retailed guide and fiber are then moved to an unprotected position (FIG. 3) so that the surface and the fiber within its ferrule may be polished on a suitable polishing wheel or similar device.
    • 纤维的轴向位置在三个研磨或抛光阶段进行控制。 首先将光纤(72)与容纳在其中的引导件(120)相冲洗。 然后将导光体的光纤端面和平面磨平。 然后将光纤抛光到其光学质量和所需的长度。 用于实现这些步骤的工具包括在工具表面(16)处保持光纤套圈(70)及其光纤(72)的保持器(74)。 该工具表面由防护罩(18)保护得太快,而纤维和纤维/导向组件与表面相冲洗。 然后将表面及其零售导向器和纤维移动到未受保护的位置(图3),使得其表面和其套圈内的纤维可以在合适的抛光轮或类似装置上抛光。

    • A system is provided for positioning a pair of electrodes on either side of the end portion of an optical fiber extending through a contact, to establish an arc through a cross-aperture in the contact and across the fiber to melt the fiber into a lens, which assures close control of the arc and which prolongs the life of the electrodes. The tips of the electrodes are positioned to lie slightly within opposite ends of the cross-aperture, to avoid establishing an arc between the electrodes which passes around the contact instead of through the cross-aperture. The electrodes are spaced apart by at least about eight times the diameter of the optic fiber, to avoid deposition of vapors from the heated optic fiber onto the electrodes. The cross-aperture extends to the tip of the contact, so the contact can be moved along its axis to a position where the electrodes lie on opposite sides of the fiber end portion.
    • 提供了一种系统,用于将一对电极定位在延伸穿过接触件的光纤的端部的任一侧上,以通过接触中的交叉孔径并穿过纤维形成电弧,以将光纤熔化成透镜, 这确保电弧的紧密控制并延长电极的寿命。 电极的尖端定位成稍微位于交叉孔的相对端内,以避免在通过接触而不是穿过交叉孔的电极之间形成电弧。 电极间距至少约为光纤直径的八倍,以避免蒸汽从加热的光纤沉积到电极上。 交叉孔径延伸到接触件的尖端,因此接触件可以沿其轴线移动到电极位于纤维端部的相对侧上的位置。

    • A binocular endoscope which uses a pair of coherent fiberoptic channels and associated objective lens systems which incorporate a "zoom" feature of magnification while preserving depth perception for the user. There are two longitudinally spaced lenses in each objective lens system. The endoscope is inserted into a body cavity and the object to be examined is brought into focus with the lenses separated at or near their minimum spacing in order to establish orientation within the body cavity. After orientation is established, the spacing between lenses is reset to be at or near its maximum distance between lenses and the scope is advanced axially to its fixed focal plane. Thereafter, the field of view and its concomitant magnification are varied without changing the axial position of the scope with respect to the patient.
    • 一种双目内窥镜,其使用一对相干光纤通道和相关联的物镜系统,其结合放大的“缩放”特征,同时保持用户的深度感知。 每个物镜系统中有两个纵向隔开的透镜。 将内窥镜插入体腔中,并且将被检查物体聚焦,以及在其最小间距处或其附近分开的透镜,以便在体腔内建立取向。 定向成立后,透镜之间的间距被重置为在透镜之间或其附近的最大距离处,并且镜面将轴向前进至其固定焦平面。 此后,在不改变范围相对于患者的轴向位置的情况下改变视野及其伴随放大倍率。
