Abstract
An augmented reality optical module includes a relay lens group and a reflection lens group. The relay lens group receives and converges the light emitted by the image source. The reflection lens group comprises a first lens and a second lens. The light emitted by the image source is incident to the relay lens group and converged to form the relay image at least once, the light of the last relay image is incident to a first surface of the first lens and reflected, the reflected light is incident to a first surface of the second lens and reflected, and then incident to the first lens and transmitted through the first lens to form imaging light. The ambient light is transmitted in such a manner that the ambient light is transmitted through the second lens and the first lens, sequentially, and then emitted to be superimposed on the imaging light.
