摘要： PURPOSE:To observe the same part to be observed from different angles by forming a tip light sensing part by a tip part of a light guide and a tip part of an image guide, and also providing two pairs of tip sensing parts as to one piece of head body, so that they turn to the same part to be observed. CONSTITUTION:A light sensing part S irradiates a light beam L from a tip part of light guides 4, 5 to a part to be observed A through a light projecting hole 20 which is provided on a cylindrical body 13, makes the light beam L which is reflected by the part to be observed A, to a tip part of image guides 6, 7 through a light receiving hole 21 which is provided on the cylindrical body 13, and a prism 19, connects it to a camera, etc. with the necked eye or through a mount which is omitted in the figure, etc., in an eyepiece part, and observes the part to be observed A. Also, the respective tip light sensing parts S, S are set so as to turn to the same part to observed A. That is to say, the light beam L is irradiated to the same part to be observed A from the light guides each is different in angle and the light beam L which is reflected from the same part concerned to be observed A is made incident on the image guides different in angle.

摘要： PURPOSE:To irradiate the internal surface of an inner cylinder with light and observe it at 360 deg. at the same time and to improve the observing operation by arranging tip parts of image guides for sideward view on a small circle at the pitch of a circumference, and arranging tip parts of a light guide for light irradiation on a large circle concentric with the small circle at the circumference pitch. CONSTITUTION:An ocular part is arranged on a fiber scope for observing a flaw and corrosion on the internal surface of a cylinder and an objective part 5 is provided atop of a long fiber scope main body. A light objective part 5a which irradiates and observes the internal surface of the cylinder at 360 deg. at the same time is provided to the intermediate part of the objective part 5. The tip parts 12a of image guides 13 are arranged on the center 45 deg. small circle of this fiber scope. Further, light guide tip parts 13a are arranged on the large circle at the equal pitch of a 45 deg. center angle on the light guide 13 made of optical fibers which transmit light from the ocular part side. Thus, the number of the image guides 12 is decreased and the small-diameter cylinder is used to observe the whole 360 deg. circumference continuously at the same time.

摘要： PURPOSE:To prevent securely an optical fiber made of quartz, etc., from deteriorating in an atmosphere where radiation is irradiated by making bleaching light which has optical energy of >=3mW per core sectional area (mm ) of an image guide incident on the ocular-side end surface of the image guide. CONSTITUTION:The laser light (bleaching light L) having optical energy of >=3mW per core sectional area (mm ) of the image guide 1 is made incident on the ocular-side end surface 27 of the image guide 1. Further, when an object part is observed, the laser light is not made incident on the image guide 1 and only when no observation is made, the laser light is made incident. Namely, the laser light is made incident intermittently. Consequently, the image guide 1 made of an optical fiber made of quartz, etc., is prevented effectively from increasing in loss in an atmosphere where radiation is irradiated, thereby preventing the image guide 1 from deteriorating owing to the radiation.

摘要： PURPOSE:To accurately detect an inspecting position by alternately fitting two kinds of reflecting rings having different reflecting characteristics respectively with a prescribed width along the longitudinal direction of an optical fiber body to form a stripe-like pattern. CONSTITUTION:Two kinds of reflecting rings 7, 8 having different reflecting characteristics are alternately fitted to the outer periphery of an optical fiber body 1 from is leading end up to its base end along the longitudinal direction to form then stripe-like pattern 9 on the outer periphery of the body 1. The width size of respective reflecting rings 7, 8 is set up to the same value and is lightness difference between white and black or the like is set up as the difference of the reflecting characteristics. When infrared rays are projected to the pattern 9 of the body 1, reflected light rays reflected from the reflecting rings 7,8 are different in accordance with the reflecting rings 7, 8. In case of inspecting an abnormal position of a pipe or the like by inserting a fiber scope into the pipe or the like, the number of reflecting rings is successively read out from the leading end of the body 1 up to an insertion port of the pipe or the like. Consequently, the position of a portion to be inspected such as an abnormal position can be accurately detected.
