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 19):
The apparatus of  claim 10 , further comprising:\n a second display to generate second images for presentation to a second eye of the user; and a second optical system configured to combine light representative of the second images with light received from the external source for provision to the second eye, wherein the second optical system includes:\n a fourth filter stack configured to convert light received from the second display to the first circular polarization; \n a fifth filter stack configured to convert light received from the external source to the second circular polarization; \n a sixth filter stack configured to reflect light having the first circular polarization and transmit light having the second circular polarization; and \n a second refractive beam splitting lens configured to transmit light received from the fifth filter stack to the sixth filter stack, wherein the fifth filter stack is oriented to reflect light received from the fourth filter stack onto the second refractive beam splitting lens.
