ABSTRACT:
In an optically multiplexed angular encoder system, encoder illuminators are sequentially enabled and detected signals are sequentially stored. Such sampling and storage of the code track signals is repeated in successive sampling windows under the control of a free-running clock such that the information required to provide a multibit angular output is available for a near instantaneous output on command.
