Abstract
A light intensity modulator array includes a first substrate with a two-dimensional array of electrodes; a second substrate with one or more electrodes; and liquid crystal located between the first substrate and the second substrate. The two-dimensional array of electrodes is arranged in a first direction and a second direction that is not parallel to the first direction. A respective electrode of the two-dimensional array of electrodes is distinct and separate from a first adjacent electrode and a second adjacent electrode of the two-dimensional array of electrodes. The first adjacent electrode is adjacent to the respective electrode in the first direction and the second adjacent electrode is adjacent to the respective electrode in the second direction. A method for tracking an eye using a device including the light intensity modulator array is also disclosed.
