Abstract
A measuring instrument includes a movable portion configured to rotate in an arc motion about a pivot portion, and an electronic position encoder configured to measure an absolute relative position between a detector portion and a scale portion, one of which forms part of the movable portion. In the detector portion, first and second scale element portions of first and second track portions are arc-shaped and parallel to each other. In the scale portion, first signal modulating scale elements are disposed along a first scale element portion according to a first signal modulating element angular spatial step θand second signal modulating scale elements are disposed along a second scale element portion according to a second signal modulating element angular spatial step θthat is different than the first signal modulating element angular spatial step θ.
