Abstract
The present invention is generally directed toward optical encoder systems and corresponding methods. One aspect of the invention is directed toward an optical encoder system that includes an optical encoder device having an input wheel. The optical encoder device further includes at least one light emitter and at least one light sensor to detect rotational movement of the input wheel. In a further aspect, the optical encoder device is coupled to a vehicle. In a still further aspect, the optical encoder device can be coupled to a control inceptor in a vehicle. In yet a further aspect, optical encoder device can include a housing so that the optical encoder device is couplable to structure as a single modular unit.
