| Abstract: | The system of optical gratings brings about Moire fringes and magnifies some displacement of an object, but it usually unable to show the backwardness or the forward ness on the motive direction. The photoelectrically detecting circuit mentioned in this paper, which can measuring the minute amount displacement and distinguish the direction of Moire fringe motion, has increased the resolution and automation of the photoelectric testing. |
