Abstract
A holographic optical element, a method for manufacturing the same and an apparatus for producing the same are provided. More particularly, the holographic optical element is capable of enhancing the brightness of an augmented image. In one example, the holographic optical element includes a plurality of optical elements combined together and has interference patterns recorded on the plurality of optical elements, respectively. The interference patterns have the same pitch and different inclination angles.
