SEQUENTIAL AND CYCLIC-SEQUENTIAL CODING F OR ANGLE AND DISPLACEMENT MEASUREMENT

A coding method for digital absolute position data registration has be en discovered compressing the information represented in n tracks for n sensors of currently known digital absolute position measurement sys tems to only one track. Moreover this coding method allows to reduce t he number of sensors independent on the resolution of the measurement system to two at most. The expected advantages for a measurement syste m based, on this so called sequential or cyclic-sequential coding are easy manufacturing, a reduced number of components and smaller dimensi ons.
