Abstract
Provided is a measuring device including a photoelectric conversion unit that receives a light beam emitted from a position measurement object by different optical path lengths and that outputs an electrical signal corresponding to intensity of the received light beam for each optical path length, and a measuring unit that measures a position of the position measurement object based on a ratio of two electrical signals out of the electrical signals by optical path lengths acquired from the photoelectric conversion unit.
