Abstract
An optical system including a first optical waveguide device, and a second optical waveguide device is provided. The first optical waveguide device includes a first light entering surface, a first light exiting surface and a first beam splitter. An image light emitted from the display enters the first optical waveguide device through the first light entering surface. The second optical waveguide device includes a second light entering surface, a second light exiting surface and a second beam splitter. The second light entering surface faces the first light exiting surface. A gap is formed between the second light entering surface and the first light exiting surface. Besides, a head-mounted display using the optical system described above is also provided.
