Eyepiece for near eye display system

摘要

An optical display system configured to transmit light along a light path to a user's eye, the display system comprising a circular polarizing reflector configured to reflect light with a first polarization from an image source, a quarter wave plate downstream of the circular polarizing reflector in the light path and configured to rotate the polarization of the light to a second polarization, and a curved linear polarizing reflector downstream of the quarter wave plate and configured to reflect the light back through the quarter wave plate along the light path in the direction of the circular polarizing reflector. The quarter wave plate further configured to rotate the polarization of the light received from the curved linear polarizing reflector to a third polarization and the circular polarizing reflector further configured to receive said light from the quarter wave plate and transmit the light toward the user's eye.

1. An optical display system configured to transmit light along a light path to a user's eye, the display system comprising:
a circular polarizing reflector configured to reflect light with a first polarization originating from an image source; a quarter wave plate positioned downstream of the circular polarizing reflector in the light path, the quarter wave plate configured to rotate the polarization of the light from the first polarization to a second polarization; and a curved linear polarizing reflector positioned downstream of the quarter wave plate, the curved linear polarizing reflector configured to reflect the light with the second polarization back through the quarter wave plate along the light path in the direction of the circular polarizing reflector; wherein the quarter wave plate is further configured to rotate the polarization of the light received from the curved linear polarizing reflector from the second polarization to a third polarization; and wherein the circular polarizing reflector is further configured to receive the light having the third polarization from the quarter wave plate and to transmit the light with the third polarization toward the user's eye.
