Abstract

A process for reconstructing a picture coupled into a fiber optical bundle 1) comprising optical fibers (2) is provided. It is immaterial for this process whether the optical fibers (2) are parallel or totally random in the fiber optical bundle (1). The prerequisite is that the launching sided and output sided coordinates of each optical fiber (2) are known. The picture coupled into the launching side (3) is reconstructed with the aid of the gray tones passed on by the optical fibers (2) to the output side (4). To this end a grid (5), comprising grid field (6) that are connected together without any gaps, is laid over the launching sided arrangement of the optical fibers (2). Assigned to each grid field (6) is a gray tone, which comprises through addition fractions of the output sided, average gray tones of all of the optical fibers (2), which are at least partially overlapped by the grid field (6), whereby such a fraction corresponds to the percentage of the area of the optical fiber overlapped by the grid field (6) to the total cross sectional area of the optical fiber (2). The grid (5) provided with gray tones is finally reproduced on a video screen.
