This paper presents, for the first time, a technique for formation of real, undistorted, orthoscopic integral images by direct pickup based on a smart mapping of pixels of an elemental-images set.
Fundamentals of 3D imaging and displays: a tutorial on integral imaging, light-field, and plenoptic systems
This tutorial begins by covering the fundamentals of geometrical optics and wave optics tools for understanding and analyzing optical imaging systems, and proceeds to describe integral imaging, light-field, or plenoptics systems, the methods for implementing the 3D capture procedures and monitors, their properties, resolution, field of view, performance, and metrics to assess.

Some recent advances in InI are reviewed, which have allowed improvement in the response of InI systems to the problems of the limited depth of field, poor axial and lateral resolution, pseudoscopic-to-orthoscopic conversion, production of 3-D images with continuous relief, or the limited range of viewing angles of Ini monitors.

Telecentric architecture is proposed for circumventing, by the pure-optical method, the residual parabolic phase distortion inherent to standard configuration of digital holographic microscopy. This…
Tailoring the axial shape of the point spread function using the Toraldo concept.
A novel procedure for shaping the axial component of the point spread function of nonparaxial focusing systems by use of phase-only pupil filters is presented. The procedure is based on the Toraldo…

A more general algorithm is reported which allows the pseudoscopic to orthoscopic transformation with full control over the display parameters so that one can generate a set of synthetic elemental images that suits the characteristics of the Integral-Imaging monitor and permits controlover the depth and size of the reconstructed 3D scene.
