what is the theory of absolute encoder！

Absolute encoder has a plurality of detectors and an optical disk having a plurality of distinct tracks. The disc generates Gray code output - Bell Labs physicist named Frank Gray - need the binary number system (unlike standard binary) continuous value a bit different. Thus, the maximum possible error (if the encoder transition between stops) only 0.5 bits. This information can be even when the encoder is temporarily closed.
Further to the absolute track, multi-turn incremental rotary optical encoder clock movement in a number of revolution. In the gear transmission design, a primary gear and encoder shaft movable secondary gear meshing, etc: each gear for its rotary encoder sensed by the electronic tracking etched disc; encoder combines all output tray counting the total number of turns of the shaft were.
