1. A viewing system, comprising:

  • an image source operable to transmit image signals; and

    a scanned beam display coupled to the image source to receive the image signals therefrom, the scanned beam display comprising;

    a light emitter array having a plurality of light sources operable to emit diverging light;

    an array of collimating elements, each of the collimating elements corresponding to at least one of the light sources and positioned to receive at least a portion of the diverging light emitted from the corresponding at least one of the light sources, each of the collimating elements configured to substantially collimate the received diverging light into respective beams; and

    an actuator system coupled to at least one of the light emitter array and the array of collimating elements, the actuator system being operable to move at least one of the light emitter array and the array of collimating elements to scan the respective beams to provide an image responsive to the image signals, wherein the image appears substantially fixed to a viewer as the viewer'"'"'s eye moves relative to the array of collimating elements.
