  • Augmented reality optical module
    Patent number: 11579446
    Abstract: Provided are an augmented reality optical module, including a first lens, a second lens, a third lens group, a first polarization modulation unit provided on a side of the third lens group and configured to modulate the light emitted by the image source into first circularly polarized light, an angle selection film provided on a first surface of one side of the first lens and configured to reflect light having an incidence angle greater than or equal to a first angle and transmit light having an incidence angle smaller than or equal to a second angle, and a second polarization modulation unit provided on the other side of the first lens and configured to modulate incident circularly polarized light into linearly polarized light.
