Abstract
컴퓨터 생성 홀로그램을 통해 생성된 디지털 홀로그램은 그 데이터량이 방대하기 때문에 저장, 전송 및 처리를 위해서는 데이터량을 줄일 필요성이 있다. 하나의 객체를 나타내기 위한 디지털 홀로그램의 데이터량을 줄이는 가장 효율적인 방법은 부호화를 수행하는 것이다. 본 논문에서는 효율적인 부호화를 위해 디지털 홀로그램을 Fresnel 변환을 도입하여 주파수 영역에서 분석하였다. 이 분석결과는 추후 디지털 홀로그램을 위한 부호화 기술의 개발 시 중요한 데이터가 될 것이다. Since digital hologram includes an amount of data as can be seen at the process of digitization, it is necessary that the data representing digital hologram is reduced for storing, transmission, and processing. As the efforts that are to handle hologram with a type of digital information have been increased, various methods to compress digital hologram called by fringe pattern are groped. Suitable proposal is encoding of digital hologram. This paper analyzed the properties of digital hologram using tools of frequency transform, assuming that a generated digital hologram is a 2D image by introducing Fresnel Transform. The analysis results of digital hologram to be proposed in this paper are being expected to be used as the core techniques for an encoding of digital hologram.
