An absolute encoder providing a multi-bit output binary code indicative of the position of a rotary or linear scale. The encoder employs a code track, which contains a serial code, and a clock track. The encoder may be either rotary or linear, and may be implemented optically, magnetically, inductively, capacitatively or by any other binary sensing technique.

Single track absolute encoder

A compensation system for a position encoder which automatically compensates for scale and other similar errors along the entire path of relative motion. The phase of the encoder signals is altered by a small amount for each small increment of relative motion to provide encoder signals compensated for the scale error. The phase correction is added to or substracted from the phase of the encoder signals depending upon the sense of relative motion.
