The second optical element is configured to be translated in three orthogonal axes, and a wavefront error sensor is configured to detect aberrations in the beam and to provide a wavefront error signal in response thereto. A processor is configured to provide a correction signal in response to the wavefront error signal, and an actuator is coupled to the second optical element and configured, in response to the wavefront error signal, to selectively translate the second optical element in one or more of three substantially orthogonal directions corresponding to the three orthogonal axes.

The device further includes an external polarizer external to the cube on the first optical axis and disposed to intercept light incident upon the first face along the first optical axis, an image source external to the cube and disposed to send a display image incident upon the third face along the second optical axis, a quarter-wave plate external to the cube and disposed to intercept a beam of light traveling along the second optical axis and passing out of the cube through the fourth face, and a mirror external to the cube and disposed to reflect light passing through the quarter-wave plate back through the quarter-wave plate and to the fourth face.
