1. An optical assembly, comprising:
a light-emitting device and a photodetector;
a partition structure defining a first space for accommodating the light-emitting device and a second space for accommodating the photodetector; and
a cover disposed over the partition structure, the cover having a first surface facing the partition structure and a second surface opposite to the first surface;
wherein a first light emitted by the light-emitting device forms a first irradiance pattern projected on the second surface of the cover, the cover has a recess recessed from the first surface of the cover, and the recess has an interface configured to direct a second light emitted by the light-emitting device so that the second light is transmitted to an outside beyond the photodetector after the second light is reflected by the second surface of the cover.
