Abstract
An optical system, a display apparatus, and smart glasses are provided. The optical system includes a transflective element, a reflective element and a plurality of microstructures. The transflective element is configured to reflect collimated incident light to the reflective element. The reflective element is configured to reflect the collimated incident light back to a light incident surface of the transflective element, so as to adjust an angle at which the collimated incident light exits. The transflective element is further configured to transmit the reflected-back collimated incident light to a target region. The plurality of microstructures are configured to adjust angles at which ambient stray light incident on surfaces thereof exits, and to scatter the ambient stray light out of the target region.
