Summary:Disclosed are an apparatus and a method for recording holographic element images using a spatial light modulator (SLM). The hologram recording apparatus comprises a record light source part outputting a source beam output from a light source by dividing into a first output beam and a second output beam; a reference beam generation part removing distortion of the first output beam, and generating a reference beam by controlling size and shape of the first output beam having distortion removed; an object beam generation part removing distortion of the second output beam, and generating an object beam; and an object beam collection part modifying the object beam with a hologram element image, outputting a signal beam, dividing the signal beam in multiple directions, and collecting the divided signal beams to radiate on the hologram film. 공간 광 변조기(SLM)를 이용하여 홀로그램 엘리먼트 이미지들을 기록하는 장치 및 방법이 개시된다. 홀로그램 기록 장치는 광원에서 출력된 소스빔을 제1 출력빔과 제2 출력빔으로 분할하여 출력하는 기록 광원부; 제1 출력빔의 왜곡을 제거하고, 왜곡이 제거된 제1 출력빔의 크기 및 모양을 제어하여 참조빔을 생성하는 참조빔 생성부; 제2 출력빔의 왜곡을 제거하여 물체빔을 생성하는 물체빔 생성부; 및 홀로그램 엘리먼트 이미지로 물체빔을 변조하여 신호빔을 출력하고, 상기 신호빔을 복수의 방향으로 분할하며, 분할된 신호빔들을 집광하여 홀로그램 필름에 입사시키는 물체빔 집광부를 포함할 수 있다.
