Description:

This Spotlight presents the 3D integral photography technique and its fundamentals, features, and practical applications. First, the basic concepts for the EIA acquisition and the 3D image reconstruction process are described. The main advantages and disadvantages of the integral photography are explained, followed by the computer-generation and digital-reconstruction methods. Finally, several examples, including 3D displays, 3D cameras, and 3D biomedical microscopy, are reviewed.

Three-dimensional (3-D) imaging systems are the appropriate technology to meet modern advanced demands, and they have been a popular topic since the 2000s. 3-D imaging techniques have been studied since Sir C. Wheatstone invented “stereoscopy” in 1838,1 but there has been renewed emphasis since the 2009 release of the 3-D movie Avatar. Generally, 3-D imaging systems acquire 3-D information of real or virtual objects, and show the 3-D images or video, including the width, height, and depth characteristics of the objects, to observers naturally (whereas conventional two-dimensional (2-D) images are unnatural). Nowadays, 3-D systems are widely used and developed in movies and various fields, and the investment in this field continues to increase.2
