Abstract

See full text

A method for synchronizing a light grid comprising a transmitting unit having a plurality of transmitters and a receiving unit having a plurality of receivers. A transmitter control unit activates the transmitters one after another in a cycle, and a receiver control unit evaluates the receivers. Each transmitter is associated with a receiver, and an activated transmitter transmits a transmission beam to its associated receiver. At least two transmission beams in the cycle are synchronization transmission beams which are emitted at a time offset from one another. The receiver control unit measures the time offset, and the synchronization transmission beams are uniquely associated with the totality of the transmission beams in the cycle on the basis of the time offset.
