Abstract
An augmented reality system (2) is disclosed for use in bright external conditions. The augmented reality system includes: a projector (6), a substantially transparent optical component (4) that provides augmented reality light to a user, and a stray light rejection layer (12). The stray light rejection layer (12) further comprises a plurality of slats (16) arranged at a plurality of respective angles to effectively reduce high angle incident light from the external environment from reaching the transparent optical component (4).
