A light intensity distribution hologram is generated through numerical calculation of the interference pattern. Additionally a phase hologram without the 0-th order diffraction is generated. The removal function for elimination of the 0-the order diffraction is introduced and the numerical reconstructions with several conditions for the removal of the 0-th order diffraction and the production of high quality numerically reconstructed images are tested and compared. The removal function is proven to be more effective at the suppression of the 0-th order diffraction compared with the DC suppression method. 한국광학회 디지털 홀로그래피에서 퓨리어 변환을 이용한 0차 회절광의 제거와 위상홀로그램의 생성에 대한 전산 모사 Computer simulation of the removal of the 0-th order diffraction by using Fourier Transform in digital holography Article 2 한국광학회지, v.15, no.1, pp.39 - 45 한국광학회지 15 1 39 45 kci ART001122246 computer holography three-dimensional image acquisition holographic interferometry
