Abstract
The present disclosure relates to a proximity sensor. The proximity sensor includes: a light emitter (for example, a vertical cavity surface emitting LASER (VCSEL)) configured to irradiate light to a target to be inspected; a first light receiver having a first crosstalk characteristic, configured to detect an external reflected light from a target to be inspected within a first detection region (for example, 0˜5 cm approximately); and a second light receiver having a second crosstalk characteristic different from the first crosstalk characteristic, configured to detect an external reflected light from a target to be inspected within a second detection region (for example, 3˜60 cm approximately) relatively further than the first detection region.
