Integration of two opto-electronic devices for data acquisition reducing external influences

Abstract

External influences in a motion control system contaminate measurement data due to various sources. Much effort has been tried to remove or reduce the external influences in order to obtain more accurate data. In this paper, we present a recipe to reduce the external influences, which is to integrate two sets of data utilizing two opto-electronic devices. The recipe is verified by experimental demonstrations using an up-down motion control system.
