Claim 0:
1. A hybrid scanner within a multiplexed light detection and ranging (LiDAR) system for executing a scan pattern of a plurality of sample pulsed wavelength-modulated coherent light beams, comprising:
a plurality of optical collimators configured such that one sampled pulsed wavelength-modulated coherent light beam is transferred to each collimator of the plurality of optical collimators;
wherein each of the plurality of collimators comprise: one or more graded-index fiber rods, where in each fiber rod is formed with a separate lens in contact with the graded-index fiber rod to provide the low numerical aperture as required of the graded-index fiber rod and the engineered graded-index lens for long-distance illumination and the higher numerical aperture required for receiving back-reflected pulsed wavelength-modulated coherent light from the object;

at least one slow-axis rotating planar mirror to receive and reflect at one least collimated sample pulsed wavelength-modulated coherent light beam and configured to rotate along a first axis to form a first-dimensional scan pattern of the sample pulsed wavelength-modulated coherent light beams;
a fast-axis rotating multi-faceted scanning mirror structured for reflecting the multiple pulsed wavelength-modulated coherent light beams configured to rotate on a second axis to form a second-dimensional scan pattern of the multiple pulsed wavelength-modulated coherent light beams;
wherein the multiple pulsed wavelength-modulated coherent light beams are transmitted to an object to determine its geometric dimensions with a combination of the first-dimensional scan and the second-dimensional scan pattern.
