Abstract
A method includes generating a first optical signal containing doublet pulses. Each doublet pulse includes a first pulse and a second pulse. The second pulses of the doublet pulses are in quadrature with the first pulses of the doublet pulses. The method also includes transmitting the first optical signal towards a target and receiving a second optical signal containing reflected doublet pulses from the target. Each reflected doublet pulse includes a first reflected pulse and a second reflected pulse. The method further includes performing in-phase and quadrature processing of the first and second reflected pulses and identifying one or more parameters of the target based on the in-phase and quadrature processing.
