Abstract
An augmented reality display system includes an image display, a linear polarization optical splitter, a phase delay sheet, a circular polarization optical reflector and a linear polarization absorption component. The image display provides a first beam with a first linear polarization direction, which is reflected by the linear polarization optical splitter to the phase delay sheet. The phase delay sheet converts the first beam into a second beam with a first circular polarization direction and transmits it to the circular polarization optical reflector. The circular polarization optical reflector converts the second beam into a third beam with a second round polarization direction and reflects it to the phase delay sheet. The phase delay sheet converts the third beam into a fourth beam with a second linear polarization direction, which passes through the linear polarization optical splitter and the linear polarization absorption component to form an image.
