Summary:Disclosed is a hologram projection system using a Risley prism. A hologram projection apparatus includes: a spatial light modulator (SLM) which modulates incident light from a light source into a hologram image and outputs the same; a light deflector which deflects the light outputted from the SLM according to a location of a pupil of a user; and a fixed focal lens which reproduces the hologram image on a focal plane by using the deflected light. 리슬리 프리즘을 이용한 홀로그램 프로젝션 시스템이 개시된다. 홀로그램 프로젝션 장치는 광원으로부터 입사된 광을 홀로그램 이미지로 변조하여 출력하는 공간 광 변조기(SLM: Spatial Light Modulator); 상기 공간 광 변조기가 출력한 광을 사용자의 동공의 위치에 따라 편향하는 광 편향기; 및 상기 편향된 광을 이용하여 초점면에 홀로그램 이미지를 재현하는 고정고정 초점 렌즈를 포함할 수 있다.
