Head-wearable display with collimated light source and beam steering mechanism
First Claim
1. An apparatus for a head-wearable display, comprising:
- a collimated light source coupled to selectively emit collimated light, wherein the collimated light source comprises a pixelated light source that generates a two-dimensional (“
2D”
) array of collimated light pixels;
a beam steering mechanism optically coupled to receive the collimated light as the 2D array of collimated light pixels emitted from the collimated light source and to angularly scan the 2D array of collimated light pixels between beam steering states that each redirect the 2D array of collimated light pixels to a different angular direction along at least one angular dimension, wherein the beam steering mechanism scans the 2D array of collimated light pixels across an eyebox, wherein the beam steering mechanism bends the 2D array of collimated light pixels by a same angle at a given time for all collimated light pixels output from the collimated light source at the given time; and
a synchronization controller coupled to the collimated light source and the beam steering mechanism to synchronize selective emission of the collimated light from the collimated light source with the beam steering states of the beam steering mechanism to repetitiously draw an image in the eyebox.

Abstract
A head-wearable display includes a collimated light source, a beam steering mechanism, and a synchronization controller. The collimated light source selectively emits collimated light. The beam steering mechanism is optically coupled to receive the collimated light and angularly scans the collimated light between beam steering states that each redirect the collimate light to a different angular direction along at least one angular dimension. The beam steering mechanism is coupled to scan the collimated light across an eyebox. The synchronization controller is coupled to the collimated light source and the beam steering mechanism to synchronize selective emission of the collimated light from the collimated light source with the beam steering states of the beam steering mechanism to repetitiously draw an image in the eyebox.
