Abstract:
An optical system includes a first filter stack configured to convert light received from a display to a first circular polarization, a second filter stack configured to convert light received from external sources to a second circular polarization, and a third filter stack configured to reflect light having the first circular polarization and transmit light having the second circular polarization. The optical system also includes a refractive beam splitting lens configured to transmit light received from the second filter stack to the third filter stack. The second filter stack is oriented to reflect light received from the first filter stack onto the refractive beam splitting lens. The optical system is implemented in augmented reality devices, such as head mounted devices (HMDs), to combine images generated by the display with light received from external sources.

Claim (Index 4):
The apparatus of  claim 3 , wherein the third filter stack comprises:\n a third quarter wave plate; and a second polarization dependent beam splitter to reflect light having the first linear polarization and transmit light having the second linear polarization.
