ABSTRACT:
The present invention discloses a scanning photoelectric microscope in which a first reference object to be measured which is mounted on a stationary support is disposed relative to a second object to be measured which is disposed on a slidable table so as to form on both sides of the first object to be measured two indication intervals, which are caused to coincide with each other for alignment. The scanning photoelectric microscope according to the present invention comprises a scanning device for scanning an image reflected from the two indication intervals formed by the first and second objects to be measured at a constant speed to effect parallel displacement, a marker device for detecting positions of a scanned image corresponding to those of motion of the scanning device, and a circuit for detecting the two indication intervals detected by the scanning device in terms of time in response to a signal from the marker device, the second object to be measured being shifted until the two indication intervals coincide with each other.
