Assignee: ELBIT SYSTEMS ELECTRO-OPTICS ELOP LTD.
Field: Optics (Instruments)
Classification: CPC H  G | IPC G  H

Claim 18:
19. The system of claim 18, wherein the controlling of the phase of each of the input optical beams comprises:
automatically, and separately changing the phase of each of the input optical beams, while comparing the measured power output value of the respective optical interference signal with at least one previously measured power output value of the respective optical interference signal; and
locking the phase of each respective input optical beam when reaching an extremum power output value of its respective optical interference signal, wherein the changing of the phase of each input optical beam is carried out directly based on the measured power output values of its respective optical interference signals, without calculating or estimating the correct phase and/or without producing any other signal associated therewith.
