Abstract
An optical imager with subcarrier multiplexing uses a source transmit beam to simultaneously emit SFM transmit beams towards a target and receives SFM receive beams reflected off the target. The SFM receive beams are combined to provide a total receive beam, and the total receive beam is combined with a reference beam having the same frequency modulation as the source transmit beam to provide a receive signal that is configured for extraction of image data associated with the target.
