1. An optical sensing system, comprising:
a first light source, configured to emit first light to a first position;
a second light source, configured to emit second light to a second position, wherein the first position is above the second position, wherein the first light is not emitted to the second position and the second light is not emitted to the first position; and
an optical sensor, configured to sense optical data generated based on at least one of the first light source and the second light source;
wherein a detecting region of the optical sensor comprises an upper half region and a lower half region, wherein a size of the upper half region is adjustable.
