Abstract
Aspects of the present disclosure provide a LIDAR system including an optical source to transmit at least a first beam and a second beam toward a target, respectively at a first original power level and a second original power level. The LIDAR system further includes an optical attenuator adapted to receive each of the first and the second beams disposed between the optical source and one or more optics. The at least one optical attenuator is to receive a controlled voltage to adjust a polarization of at least one of the first beam or the second beam to a first polarization. The first and the second beams are transmitted toward a corresponding local oscillator resident on the LIDAR system, such that an output of the first beam and an output of the second beam transmitted through the local oscillator are balanced to have a substantially equal power level.
