Abstract
Most users desire to migrate from two-dimensional (2D) displays to three-dimensional (3D) displays, but reality is that such migration is not occurring because currently available systems have numerous limitations and do not meet user expectations. User dissatisfaction comes from the fact that current 3D systems are not able to provide realistic images that stimulate the main mechanisms of the human visual system involved in 3D perception. Integral Imaging, along with Holography, is the only technique capable of providing the human brain with the proper physical and psychological clues for 3D perception. Integral Imaging systems can work in different configurations and technical requirements may be very different depending on the applica-tion. The most commonly used configurations of these systems and a classification based on their utility will be analyzed in this Thesis. There are some intrinsic limitations of the Integral Imaging technique that needs to be overcome to make it viable as a 3D display technique. Among these limitations are: the low resolution and the pseudoscopic nature of the reconstructed images, the inhomogeneities in the lateral resolution, the facet braiding phenomenon and the limited depth of field in the capture stage. Such limitations will be studied in this Thesis and some solutions will be proposed in order to contribute to the viability of the technique. Additionally, the number of scientific and technical applications based on Integral Imaging has grown rapidly in recent years. Throughout this Thesis, there have been proposed a couple of technical applications that include a method for analyzing the stresses within thin plates having mutual occlusions and a system that allows carrying out real scale reconstructions of 3D objects, including color and texture.
