멀티프레임 환경에 적합한 그리드 컴퓨팅 기반 디지털 홀로그램 생성 기법

Abstract

Hologram is a technic for record and reconstruction of a scene or object, and the technic is regarded as the final destination of the display technology. To generate optical hologram, however, well-controlled environment such as anti-vibration and darkroom, and expensive optical equipments are required. The requirements can be resolved through digital generation, and there are many researches about digital hologram generation. In digital hologram generation, there still remains a problem that is high computational complexity, and the problem also has been studied accordingly. As a part of the studies, in this paper, we proposed a technique for digital hologram generation based on grid computing. The proposed method is more proper for a multi-frame environment than a single frame environment and we verify that the method can generate digital holograms for 150 frames in about 10.39 seconds with four calculation clusters in the experiment.
