1. A light detection and ranging (LIDAR) system defining a first axis and a second axis, the LIDAR system comprising:
a first plurality of emitters, at least one of the first plurality of emitters being configured to emit a first laser beam at a first wavelength;
a second plurality of emitters, at least one of the second plurality of emitters being configured to emit a second laser beam at a second wavelength that is different than the first wavelength; and
an optic configured to direct the first laser beam and the second laser beam in a first and a second direction, wherein directing the first laser beam and the second laser beam in the first and second direction respectively widens a field of view of the LIDAR system along the second axis.
