The invention relates to an arrangement for optical data information transmission for geodesic devices. The object of the invention is to replace the data information transmission with mechanical-electrical contacts by optical data signal transmission which is designed in such a way that the data information can be transmitted more quickly, more simply, in a plurality of channels simultaneously and in two directions. To achieve this, the transmission of the electric signals converted into optical signals together with the visual image information is provided through one or more axes of rotation by means of the optical mapping systems following the ray fusion in a first structural unit, the ray paths for these signals being disposed coaxially in relation to the axes of rotation, and a second structural unit is provided for the ray division. By means of the invention, it is possible to eliminate the disadvantages of the mechanical-electrical contact transmission of data, to reduce the susceptibility to interference of the data information transmission, to reduce the measuring and manufacturing cost and to transmit the data information without increased technical cost in a plurality of transmission channels simultaneously and in two directions without reciprocal interference during the data transfer. |
