摘要： The invention provides a rigid endoscope utilizing a high refractive index (HRI) tunnel rod, preferably made of glass, for transfer of image light from a distal end to a proximal end of the device, such HRI tunnel rod being modified so that a minimum of light is scattered and reflected within the rod, thus minimizing veiling glare and contrast reduction of the image which is formed near the HRI tunnel rod's proximal end. The HRI tunnel rod shortens the apparent distance from the proximal to the distal end by virtue of its refractive index being greater than that of air, and also provides a light tunnel which can carry the image over a relatively long distance by virtue of its modified inside walls. A preferred method of modification includes hydrogen firing of the HRI tunnel rod in order to create a thoroughly blackened inner surface which is highly non-reflective, even at grazing incidences. Relatively simple lenses are incorporated at the ends of the rod for image formation so as to cover a wide object field and to relay the image to a video camera. Stereo measuring embodiments of the endoscope provides dual optical paths for yielding two images containing parallax data.

摘要： A side-firing laser fiber is provided with a directional indicator for use in determining the orientation of radiation to be emitted from the laser fiber. The laser fiber has an elongate core clad with a nylon jacket. Over a portion of the nylon jacket is placed a sleeve of heat shrinkable material. The sleeve is positioned over the jacket near the distal end of the laser fiber and is heat treated as to be joined to the laser fiber. Biocompatible ink is then applied to the sleeve to form a linear marking capable of delineating the direction of radiation to be emitted from the side-firing laser fiber. In use, the linear marking is oriented in the direction in which the radiation is to be emitted and the laser is then activated. This technique is particularly useful when the distal end of the side-firing laser fiber is obscured from view. The portion of the laser fiber to which the sleeve is attached is still visible when the distal end of the laser fiber is obscured. By utilizing the portion of the linear marking which is still visible, a user can direct the emission of radiation in an advantageous manner.
摘要翻译：侧射激光光纤设置有用于确定从激光光纤发射的辐射的取向的方向指示器。激光纤维具有包裹尼龙外套的细长芯。在尼龙护套的一部分上放置有可热收缩材料的套管。套筒定位在靠近激光光纤远端的套管上，并被热处理以与激光光纤接合。然后将生物相容的油墨施加到套筒上以形成能够描绘从旁路激光光纤发射的辐射方向的线性标记。在使用中，线性标记沿着要发射辐射的方向定向，然后激活激光。当旁路激光光纤的远端被遮挡时，该技术特别有用。当激光光纤的远端被遮挡时，套筒附着的激光光纤的部分仍然可见。通过利用仍然可见的线性标记的部分，用户可以以有利的方式指导辐射的发射。

摘要： The present invention is an optical probe for emission of light from a region smaller than a wavelength. The optical probe includes a transmission line fed by an optic fiber and an impedance matched coupling. In a first embodiment the optical probe ends with a surface-wave transmission line including a central conductor and a coaxial dielectric. The diameter of the central conductor at the optic fiber is selected to substantially match the transmission impedance of the surface-wave transmission line to that of the optic fiber. The diameter of the central conductor decreases to a diameter smaller than the use wavelength at the tip end. The far end of the dielectric preferably includes a concavity to shape the resulting electric fields. In an alternative embodiment, the optical probe includes a coaxial transmisson line. The optic fiber includes a section having a decreasing diameter outer cladding and a section having no outer cladding. The coaxial transmission line includes a central conductor and a dielectric having a diameter substantially equal to the diameter of the core. An outer conductive layer is concentric with the two sections of the optic fiber and the dielectric. In a further alternative embodiment the impedance matched coupling includes a resonant cavity tunable to minimize the voltage standing wave ratio in the optic fiber.

摘要： A system is provided for delivering a high-power laser beam through a fiber optic cable to a metal workpiece for drilling, cutting or welding the workpiece. The laser beam is focused onto a first end of the fiber optic cable, with a gas being applied to the first end of the cable as a cooling agent. The gas is transmitted coaxially with the fiber optic cable along the length thereof. The laser beam emerges from a second end of the fiber optic cable and is received and focused onto a workpiece by a beam delivery assembly. The transmitted gas is applied to the second end of the fiber optic cable as a cooling agent and injected onto the workpiece coaxially with the focused laser beam. With such arrangement, a laser beam is delivered to a workpiece for processing the workpiece via a flexible system, allowing the beam to be dexterously maneuvered about the workpiece. Also, since the gas cooling agent is applied to the workpiece coaxially with the focused beam, the gas may comprise an element which assists the laser beam in processing the workpiece. Also included is a mechanism for facilitating connection of the beam delivery assembly to an arm for maneuvering the beam delivery assembly through a plurality of positions with respect to the workpiece. Such mechanism inhibits rotation of the beam delivery assembly and the fiber optic cable during such maneuvering, thus preventing rotational strain from being applied to the cable and reducing the possibility of cable breakage.

摘要： A contra angle handpiece of this invention employs a laser beam transmitting glass fiber for dental treatment in such a manner that the transmission of the beam is carried out not by a reflecting mirror, but by a glass fiber centripetally held with respect to the handpiece by means of resilient grip members. As a result, the disadvantages of the prior art such as reflection factor reduction and reflection angle changes, which result from the use of a reflecting mirror in a contra angle dental handpiece, are eliminated.
