Patent ID: 8811825

Claim:
A method for optically transferring data between a transmitter and a receiver, comprising: providing a color coding method based on a plurality of elementary colors for encoding and transferring the data, transmitting each elementary color by at least one respective optical radiation source on the transmitter side and receiving each elementary color on the receiver side by at least one respective optical radiation receiver, forming a control loop between the transmitter and the receiver, transmitting calibration messages from the transmitter to the receiver, determining by the receiver a compensation factor comprising or based on a number vector including diagonal elements of a compensation matrix determined from a channel property matrix of at least one received calibration message and a corresponding channel property matrix of at least one previously received or stored calibration message, based on the determined compensation factor, the receiver transmitting compensation information to the transmitter, and adjusting at least one transmitting parameter in the transmitter based on the determined compensation information.
