Patent ID: 11909167
Assignee: ELBIT SYSTEMS ELECTRO-OPTICS ELOP LTD.
Field: Optics (Instruments)
Classification: CPC H  G | IPC G  H

Claim 2:
3. The method of claim 1 further comprising controllably changing phase of each of the input optical beams, based on the measured power output value of its respective optical interference signal,
wherein the controlling of the phase of each of the input optical beams comprises the steps of:
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 from the respective optical detector; and
locking the phase of each respective input optical beam when reaching an extremum power output value from the respective optical detector,

wherein the changing of the phase of each input optical beam is carried out directly based on the measured overall power output values of its respective optical interference signals.
