| titleOfInvention | Optical position measuring device |
| abstract | The appliance has a measurement scale (M) and a scanning unit (A) linked to the objects the positions of which are to be measured. The scanning unit has a scanning panel (AP) with at leasst two scanning zones (AF1,AF2) forming scanning scales which are offset from one another in the measurement direction (x) by a fraction (D) of the divisions (TP) of the measurement scale. Optical deflection elements (AE1,AE2) separate spatially the individual signals defined by the scanning zones which are phase displaced to one another by 900. Pairs of detector elements (D11,D12,D21,D22) detect the individual signals in different directions in space. Each pair is connected anti-parallel so that two output signals phase displaced by 900 are obtained for subsequent processing. The offset between the scanning zones is given by :- D = TP/2 * (N + 1/4) With N = 0,1,2..... |
