PURPOSE:To provide an observing device for optical fiber which can do without moving an image pickup body such as a CCD camera. CONSTITUTION:The light is radiated from two directions by light sources 4A and 4B, and these light are crossed with each other on the axis of optical fiber 1 to be observed, and magnifying lenses 5A and 5B are arranged on the respective optical axes of the light passing through the optical fiber 1, and mirrors 6A and 6B are arranged on the respective optical axis extension lines of the light passing through the magnifying lenses 5A and 5B, and a half mirror 7 is arranged on the optical axis extension lines of the light reflected by both mirrors 6A and 6B as well as in a position where both optical axes cross each other, and an image pickup body 8 is arranged in a position to form an image from optical fiber images on extension lines of the optical axis of the passing light and the optical axis of the refracted light. Thereby, the optical fiber images observed from two directions can be simultaneously and simply observed even by anyone without moving the image pickup body. |
