Method and device for the detection of eavesdropping tests in optical space Data transmission

摘要

A method for interference-proof optical data transmission is achieved according to the invention in that a high-frequency screen in the form of a radio link is constructed around the optical beam, detects the distribution of the field strength and thus regulates the alignment of the antennas, the orientation of the optical transmitter and receiver is supported and disturbing Objects that move between the receiver and the transmitter are detected by partial attenuation of the edge transmission, or that are constructed around the optical beam more concentrically arranged optical channels, with which the alignment of the optical transmitter and receiver is supported and disturbing objects that intervene Push receiver and transmitter, be detected by partial failure or attenuation of the edge transmission, the radio link or the other optical channels is always set up only short term /, with duration and repetition rate of the Relativgeschwindig between the antennas or the optical transmitter and receiver and the propagation ratios of the electromagnetic waves depends.
