Abstract
An optical apparatus includes an image source, a scanning mirror, an actuator, and a scanning controller. The image source outputs an image by simultaneously projecting a two-dimensional array of image pixels representing a whole portion of the image. The scanning mirror is positioned in an optical path of the image to reflect the image. The actuator is coupled to the scanning mirror to selectively adjust the scanning mirror about at least one axis. The scanning controller is coupled to the actuator to control a position of the scanning mirror about the at least one axis. The scanning controller includes logic to continuously and repetitiously adjust the position of the scanning mirror to cause the image to be scanned over an eyebox area that is larger than the whole portion of the image.
