Abstract
An optical sensor includes a time difference extraction circuit for extracting a time difference based on the distance to a target on the basis of a first received light pulse signal from a first light receiving unit, a reference cycle, and a second received light pulse signal from a second light receiving unit, and a determination circuit for determining whether a crosstalk value can be calculated on the basis of the time difference extracted by the time difference extraction circuit and the reference cycle.
