Abstract
A optical device includes a waveguide plate, which includes an in-coupling element to form first guided light (B) and a second guided light (B) by diffracting input light (IN), an expander element to form third guided light (B) by diffracting the first guided light (B), an out-coupling element to form first output light (OB) by diffracting the third guided light (B), a bypass element to form fourth guided light (B) by diffracting the second guided light (B), wherein the first guided light (B) propagates in a first direction, the second guided light (B) propagates in a second direction, and the angle γbetween the first direction) and the second direction is in the range of 60° to 120°, wherein the out-coupling element includes one or more augmenting regions.
