초록

3차원 물체의 합성된 컴퓨터 형성 홀로그램(CGH)을 새로운 형태의 3차원 좌표변환 기술을 사용하여 제작하였다. 제작될 3차원 물체는 CCD 카메라를 사용하여 시야각도(viewing angle)를 변화시키면서 여러개의 영상으로 기록하였다. 이렇게 얻어진 영상 데이터는 2차원 복소 매트릭스를 사용하여 수학적인 방법으로 계산되고, 최종적으로 합성된 3차원 CGH로 부호화하였다.

Synthesized 3-D CGH of a general three dimensional object is obtained by using a new 3-D coordinates transformation technique. A CCD camera is used to record several projected images of the 3-D object from different viewing angles. The recorded data are numerically calculated and processed to yield two-dimensional complex functions, which are then encoded fer the final synthesized 3-D CGH.
