Abstract

In this Paper, new data matrix structure and respective processing algorithm for digital holographic storage are Proposed. Data matrix consists of user data and reference grid which is used to compensate geometrical errors such as magnification, shift and rotation of stored information. Processing algorithm identifies the location of reference grid and extracts user data. As a result of experiment, raw BER in case of shit, rotation and magnification are 3.09${\times}$10$^{-18}$ , 6.14${\times}$10$^{-12}$ , 1.2${\times}$10$^{-7}$ , respectively.

디지털 흘로그래픽 정보 저장을 위한 새로운 데이터 매트릭스 구조와 이 구조를 통해 정보 추출할 수 있는 알고리즘을 제안하고 구현하였다 제안된 데이터 매트릭스 구조는 실제 사용자 정보와 기하학적 변형에 따른 raw BER을 줄이기 위한 참조 격자로 이루어져있고, 정보를 추출하는 알고리즘은 찬조격자의 위치를 판별하고 이 정보로부터 실제 사용자 정보를 추출하는 구조로되어 있다. 실험 결과 영상 이동, 회전, 배율변화에 대해 각각 3.09×10-18, 6.14×10-12, 1.2×10-7 의 평균 raw BER을 얻음으로서, 기하학적 변형에 대한 우수한 검출특성을 갖고 있음이 증명되었다.
