Abstract
An offset correction system for correcting signal offset of an encoder. The offset correction system may include a light emitter, an encoder disk, a reticle, a light detector; an offset detection circuit and an offset correction circuit. The offset detection circuit may comprise a comparator and an offset detector configured to receive sinusoidal output signals from the light detector and a reference signal to create digital pulses for determining the signal offset. The offset correction circuit may be configured to apply a gain to correct the offset output signal. The offset correction may be implemented in real time mode.
