OPTICAL SENSOR, OPTICAL TESTING DEVICE, AND OPTICAL CHARACTERISTIC DETECTION METHOD
摘要
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.
