Abstract: This disclosure relates to a glasses-type augmented reality apparatus, and system with compact dimensions. An aspect of the present embodiment provides an augmented reality apparatus which provides a wearer with a digital holographic image incident from the outside as a holographic image, the apparatus including a plurality of holographic optical elements (HOEs) arranged in the form of concentric circles having different radii inside an optical configuration worn by the wearer to diffract the incident digital holographic image and provide the diffracted digital holographic image to the wearer.
