Abstract
A light sensing system includes a plurality of light-emitting devices arranged to have a first optical axis and a plurality of light-receiving devices arranged to have a second optical axis, the second optical axis being parallel with the first optical axis. The plurality of light-emitting devices and the plurality of light-receiving devices are formed to have a monolithically integrated structure, and the first optical axis and the second optical axis are substantially coaxial to each other, thus improving the efficiency of light reception.
