[0003] 이에 따라, 입체 영상을 표시하기 위한 장치에 대한 수요가 증가하고 있으며, 이러한 사회의 요구에 맞추어 입체 영상 기술이 영화를 통하여 제안되어 왔으며, 이러한 기술로는 가상 현실을 이용한 기술, 즉 홀로그래피 기술을 이용하여 입체 영상을 구현하는 기술 등이다.[0003] Accordingly, the demand for a device for displaying a 3D image is increasing, and a 3D image technology has been proposed through movies to meet the needs of such a society. As such technology, a technology using virtual reality, that is, holography It is a technology that implements a 3D image using technology.

[0004] 일반적으로 평면거울 반사에서 우리가 물체를 볼 수 있는 것은 물체에서 반사된 빛이 우리 눈으로 들어오기 때문이다.[0004] In general, the reason that we can see an object in a plane mirror reflection is because light reflected from the object enters our eyes.

[0005] 가상의 영상을 보는 방식은 대표적으로 3D 안경을 착용하고 보는 방식이다. 다른 방법으로는 홀로그래피 기술을 이용하여 공간에 홀로그램 영상을 구현하는 방식으로 홀로그래피 기술을 적용한 입체 영상을 기록하고 재생하는 기술이 많이 집중되고 있다. 현재 홀로그래피 기술은 홀로그램을 활용한 전시용과 박물관등에 설치되어 있는 홀로그램이 그 대표적인 활용 예에 그치고 있다. [0005] A method of viewing a virtual image is a method of viewing while wearing 3D glasses. As another method, a technique for recording and reproducing a stereoscopic image to which a holographic technique is applied is a method of implementing a holographic image in a space by using a holography technique. Currently, holography technology is only used for exhibitions using holograms and holograms installed in museums.
