Description

Optical device Technical Field The disclosure relates to an optical device. Background Augmented reality refers to a technique of superimposing virtual images on a real image seen by the eyes of a user and displaying them as one image. The virtual image may be a text image or a graphic image, and the real image may be information about a real object observed in a field of view of the device. Augmented reality may be implemented using head-mounted displays (HMDs), heads-up displays (HUDs), and the like. An optical device for providing augmented reality may include an optical member that provides a virtual image displayed on a display device to an eye of a user by changing an optical path of the virtual image. The optical device may further comprise a condenser for focusing the virtual image of the display device on the optical member. Since the distance between the display device and the optical member is small, the thickness of the condenser can be increased to increase the refractive power.
