摘要
An optical device comprises a first incidence plane (12) configured to enter rays coming from a first direction, a second incidence plane (14) configured to enter rays coming from a second direction different from the first direction, the rays entered the first incidence plane (12) being reflected by the second incidence plane (14), the rays entered the second incidence plane (14) being reflected by the first incidence plane (12), and an emission plane (16) configured to mix the rays reflected by the first and second incidence planes (12, 14) and to emit in a predetermined direction different from the first and second directions.
