Holographic optical elements (HOEs) exhibit several unique properties in arbitrary wavefront recording and extraction. Versatile recording mechanisms and material availabilities further expand their design flexibilities. Augmented reality (AR) displays are emerging and transforming daily life. Applications of HOEs in AR have harvested numerous fruitful evolutionary and revolutionary progresses. Herein, the basic operation principles of HOEs are elucidated, recent advances in AR systems are reviewed, and their future perspectives are discussed.
