Abstract

An augmented reality (AR) display device is described. The display device includes a projection source; a first optical path having a first beamsplitter and a first reflector; and a second optical path having a second beamsplitter and a second reflector. The first and second reflectors each include a reflective film. Virtual image light emitted from the projection source and carrying virtual image information first passes through the first optical path where it is reflected at least twice and transmitted at least once by the first beamsplitter and the first reflector, then enters the second optical path where it is transmitted at least once and reflected at least twice by the second beamsplitter and the second reflector, and enters a human eye. Scene light from a real scene enters the human eye through the second optical path. A wearable AR system can include the AR display device and the projection source.
