Abstract

1,245,912. Measuring displacement. WERKZEUGMASCHINENFABRIK OERLIKON BUHRLE A.G. 13 Jan., 1970 [24 Jan., 1969], No. 1656/70. Heading G4H. [Also in Division G1 Eleven photo-cells F 1 -F 11 (Fig. 3) positioned a distance b1/ 10 b apart sense a grating having marks of width b as it moves, the photo-cell outputs being connected in pairs to ten differential amplifiers DV1-DV10, the outputs from which are used to determine the displacement of the grating. As described, the image of a scale (3, Fig. 1, not shown) is projected in front of a mask (M) having apertures (A) behind which are positioned the photo-cells (F). The resolution of the system may be increased by differentiating the output signals from the differential amplifiers.
