Abstract
Motion detection device consisting of a single encoder and a single stationary sensor element, the encoder, which is arranged on a movable part, representing an asymmetrical pattern. The angular velocity or velocity and the direction of motion of a moving part are determined from the sensor signal by measuring the edge steepness or the rise time or fall time, spectrally analyzing the frequency and the phase relation of a harmonic to the phase of the fundamental mode, or evaluating the asymmetries of a sequence of rectangular pulses.
