REFERENCE SIGNAL GENERATION APPARATUS FOR POSITION DETECTOR |
摘要 |
A reference signal generation apparatus for a position detector is disclosed in which a plurality of signals having peaks at predetermined intervals are produced from the light transmitted through slit rows of random patterns and a plurality of light detectors for detecting the same light, thereby producing a reference signal in the vicinity of maximum and minimum values of the difference signal between the output signals of the light detectors. |
