Beschreibung
Zusammenfassung:	Disclosed are an optical device, a display apparatus including same, and a method for extending an optical path. The disclosed optical device comprises: at least one electroactive optical cell capable of adjusting the phase profile of light; and an optical path extender configured such that light passes through the electroactive optical cells a plurality of times in two opposite directions, thus extending the optical path of the light. L'invention concerne un dispositif optique, un appareil d'affichage le comprenant, et un procédé d'extension d'un trajet optique. Le dispositif optique de l'invention comprend : au moins une cellule optique électroactive apte à ajuster le profil de phase de la lumière ; et un prolongateur de trajet optique conçu de telle sorte que la lumière traverse les cellules optiques électro-actives une pluralité de fois dans deux directions opposées, prolongeant ainsi le trajet optique de la lumière. 광학 장치, 이를 포함한 디스플레이 장치 및 광 경로 확장 방법이 개시된다. 개시된 광학 장치는, 광의 위상 프로파일을 조절할 수 있는 적어도 하나 이상의 전기 활성 광학 셀; 및 광이 상기 전기 활성 광학 셀을 서로 반대 방향으로 광 복수 회 투과하도록 하여 광의 경로를 확장시키도록 구성된 광 경로 확장기;를 포함한다.
