Abstract
An optical navigation system having two or more optical pipelines for image acquisition and a single multiplexed optical array. Each of the two or more optical pipelines for image acquisition may include an illuminator that emits optical radiation at a navigation surface where each navigation surface is separate from the other navigation surfaces. The single multiplexed optical array may be configured to receive optical radiation reflected from the respective navigation surfaces. The optical navigation system may further include illuminator drivers that control each of the optical pipelines for image acquisition and an optical sensor that is configured to multiplex the images recovered by the optical pipelines for image acquisition and perform image correlation for the different navigation surfaces.
