Abstract

PURPOSE:To make observation quick and improve reliability by so constituting the device that the beginning ends of plural pieces of optical fibers provided with a condenser lens oppose to a hole wall surface, and the developed image of the hole wall in 360 deg. directions is obtained at the final end faces of this bundle. CONSTITUTION:P1, P2 are respectively the 1st-i-th optical fiber groups for observation. In the end part PE above these, the end faces of the optical fibers of the respective optical fiber groups are arranged in an X-axis direction respectively in order of suffix numbers. The respective groups are arraged in an Y-axis direction in order of the suffix numbers of the 1st optical fiber thereof. The lower end of the respective optical fibers are located diametrically to the hole wall surface by leaving a constant spacing l in the depth direction by each group and are bent so as to assume radial disposition having a prescribed spacing at the same opening angles determined by angles theta2 of view. A condenser lens L4, an image pickup tube IS, etc. are coupled to a molded resin body M, and the image output signal is connected to a television receiver by means of a cable OC. With such constitution, the observation is made quick, and since there are no movable parts, the reliability is improved.
