A retinal scanning display system that produces multiple focal planes with a deformable membrane mirror
A microelectromechanical system (MEMS) deformable membrane mirror is used to generate realistic 3D depth cues by variable focus. The monocular laser scanning display creates multiple focal planes that are optically superimposed over real world objects allowing augmented reality views to be registered in three dimensions. The display allows the viewer to see 3D objects using the natural accommodative response of the eye, unlike common stereographic displays, which uncouple the accommodation response. The MEMS deformable mirror varies a laser beam divergence simulating a beam from optical infinity to 33 cm distance (03D). Measurements in human subjects show that subjects accommodated appropriately to the display.
