Abstract

In this paper, we present a speckle-free digital hologram with conversion to an off-axis horizontal-parallax-only (HPO) hologram. First, we record the speckle-free hologram using optical scanning holography. Second, we digitally convert the full-parallax hologram to a horizontal-parallax-only hologram. Third, we convert the horizontal-parallax-only hologram to an off-axis hologram. Finally, we show that the off-axis HPO hologram can be numerically reconstructed in space.

본 논문에서는 광 스캐닝 홀로그래피 기술을 이용하여 실제 반사형 물체의 복소 홀로그램을 스펙클 잡음 없이 촬영하고 데이터양을 줄이면서 동시에 일반적인 진폭 유일 공간 광 변조기를 이용해 광학적인 방법으로 복원할 수 있도록 탈축 수평 시차 홀로그램으로 변환하였다. 변환된 탈축 수평 시차 홀로그램이 공간상에 복원되어 디스플레이가 될 수 있음을 보이기 위하여 수치적인 방법을 이용하여 홀로그램을 복원하였다.
