Abstract
A method for optical measuring data acquisition of a component that moves in a rotary or translatory manner, in particular for optical angle, torque, or distance measurement, includes generation of a first pair of periodic line patterns extending in the movement direction of the component and a second pair of periodic line patterns extending in the movement direction of the component, which each have m periods, in particular n+1 periods, over the movement range of the moving component determination of respective phases of the line patterns of the first pair and of the second pair, determination of the phase position of the first pair of line patterns on the basis of the phases and of the second pair of line patterns on the basis of the phases, and determination of the position of the component on the basis of the phase positions.
