OPTICAL POSITION SENSOR AND POSITION DETERMINATION METHOD
摘要
A method of position measurement by processing at least two phase displaced signals and by selecting one signal for position measurement at a given position point. Specifically, the two phase displaced signals are quadrature signals and the selected signal has a more linear wafeform slope relative to time at a given position point than the non-selected signal.
