기존 2D 카메라로 획득된 영상은 공간에 존재하는 빛에 대한 손실된 정보를 담고 있어 그 응용에 한계를 가지고 있다. 그러나 공간 내에 존재하는 빛 정보를 획득하여 가지고 있다면 그 공간을 똑같이 인위적으로 다른 장소에서 그대로 재현해 낼 수 있어 다양한 분야에 응용할 수 있을 것으로 기대된다. 근래에 이러한 빛 정보를 획득하기 위한 카메라 기술 및 장치들에 대한 연구개발이 활발히 진행되고 있다. 본고에서는 공간에 존재하는 빛 정보를 나타내기 위한 light field 개념을 소개하고, light field 정보 획득 카메라 기술 및 장치에 대해 살펴본다. 또한 기 개발된 light field 카메라들의 특징들을 비교 분석하고, 다양한 응용 사례에 대해 알아보기로 한다.
