Abstract
An optical sensor includes an irradiation system including at least one light irradiator to irradiate light onto an object under test; and a detection system detecting the light that is irradiated from the irradiation system and is propagated in the object under test. Further, the light irradiator irradiates non-parallel plural light beams on a same position of the object under test.
