Abstract
PURPOSE: To achieve simultaneous measurement of speed and position of a travelling body, with high precision and without mechanical contact to the travelling body, by detecting light transmitted through a pair of elongated parallel slits formed in the travelling body and through a slit group arranged in a plurality of vertically spaced rows which involve a different number of slit elements from each other.
