디지털 홀로그래피 현미경을 통해 획득한 간섭무늬는 시료의 두께 정보를 포함하고 있다. 하지만 데이터의 용량이 크다는 단점이 존재한다. 따라서 간섭무늬가 담고 있는 시료의 두께 정보 손상을 최소화하면서 데이터 크기를 줄일 수 있는 압축 방법이 요구된다. 본 논문은 위상 압축 방법을 제시하여 JPEG Pleno Holography에서 사용되는 간섭무늬 압축 방법보다 위상 압축 방법이 더 효율적임을 실험을 통해 확인했다. RMSE와 BD-Rate 그리고 PSNR을 사용하여 평가한 결과 위상 압축 방법이 간섭무늬 압축 방법보다 최고 92.39% 향상된 성능을 보였다. 또한 다양한 조건 아래에서 실험을 진행하여 조건 별 압축 성능을 비교분석 했다. 간섭무늬 압축 방법의 경우 시료의 두께를 계산하기 위한 위상 정보뿐 아니라 다른 정보들도 포함하고 있음에 반해, 위상 압축 방법은 간섭무늬에서 불필요한 정보들을 제거 후 위상에 대한 정보만을 압축하는 방식이기 때문에 더 높은 성능을 보이는 것으로 판단 된다.
