A method for eye-safe operation of a pulsed noise laser in a DIRCM system

摘要

A method for operating a pulsed interference laser in an eye-safe manner in a DIRCM system onboard an aircraft is provided. A reception apparatus is used to receive echoes from the emitted pulses from the interference laser and to evaluate them to determine whether an object is situated within a prescribed laser safety distance for the DIRCM system in the laser beam. The emission of the laser beam is enabled separately for a respective period of time t within the period of use of the interference laser, the emission being enabled for the respective subsequent period of time t only if no object has been found within the laser safety distance within the respective preceding period of time t.
