Abstract: 971,504. Electric selective signalling systems. ELECTRIC & MUSICAL INDUSTRIES Ltd. Feb. 6,1961 [Feb. 5, 1960], No. 4093/60. Heading G4H. A system for measuring the relative displacement of two members by counting MoirÚ fringes produced by two diffraction gratings, is characterized in that MoirÚ fringe patterns of higher order than the usual pattern are also sensed in order to provide a more accurate measure of the displacement. According to the Specification a lamp 5, Fig. 1, mask D, lens L1, L2 will produce a zero order MoirÚ fringe pattern at a point on the focal axis. Higher order patterns are produced at other points on the focal plane, and they have the property that where, in a certain distance e Fig. 2(a), the first order pattern has one line, the second order Fig. 2(b) will have two, and the fourth order Fig. 2(c) four. Thus by sensing these higher order patterns a more precise measurement is possible. In the preferred embodiment the first, second,fourth and eighth patterns are used, the fringes from the first order being counted, the other fringes being used, via a recording network, to indicate a fine diversion of the count.
