Claim 11:
12. The lidar sensor system of claim 10, wherein the optical transmitter includes:
a phase shifter coupled to receive the light beam from the stable light source and configured to phase shift the light beam by approximately 90 degrees to produce a phase shifted light beam;
a first mixer coupled to the stable light source and to an output of the baseband modulator, the first mixer configured to apply the baseband modulation to the light beam from the stable light source to produce a first modulated light beam;
a second mixer coupled to an output of the baseband modulator and to an output of the phase shifter, the second mixer configured to apply the baseband modulation to the phase shifted light beam to produce a second modulated light beam; and
an optical combiner configured to combine the first modulated light beam and the second modulated light beam to produce a modulated transmit light beam for transmission into the target area.
