1. A plurality of optical modules, each optical module comprising:
a light source configured to output light; and
a micro lens array (MLA) module on a front side of the light source positioned to receive the light,
wherein the MLA module includes:
an input lens array through which the light is input, the input lens array including a plurality of input lenses; and
an output lens array provided on a front side of the input lens array and configured to output the light received through the input lens array, the output lens array including a plurality of output lenses,
wherein optical axes of all of the plurality of output lenses in the output lens array extend in a forward/rearward direction and cross respective centers of the plurality of input lenses;
the input lenses have shapes that are convex in a rearward direction,
the output lenses have shapes that are convex in a forward direction; and
the input lenses have upper portions and lower portions, and
radii of vertical curvatures of lower portions of the input lenses are larger than radii of vertical curvatures of the output lenses, and
radii of vertical curvatures of upper portions of the input lenses are the same as radii of vertical curvatures of the output lenses, and
a collimator configured to convert the light output from the light source to parallel light, the collimator being disposed between the light source and the MLA module with respect to the forward/rearward direction, and
wherein the direction in which the collimators are arranged is different for each of the optical modules of the plurality of optical modules.
