An optical profile detector is provided in which a light pattern projected upon the surface of a specimen is varied depending upon the profile of the specimen; and the projected light image is scanned into electrical signals which in turn are shaped into pulses so that the deviations in profile of the specimen from the standards may be detected from the deviations of the time intervals between the pulses from a predetermined time interval.
