TLDR
In this paper, a recursive design technique was proposed to record the final hologram with complex wave fronts derived from intermediate holograms, and the design was illustrated for a lens with an f-number of 2.5 and a large offset angle, recorded at 488 nm and read out at 633 nm.Abstract:
A method for designing and recording transmission holographic lenses, having low aberrations and high diffraction efficiencies, in the presence of a recording–readout wavelength shift, is presented. The method is based on a recursive design technique, in which the final hologram is recorded with complex wave fronts that are derived from intermediate holograms. The design is illustrated for a lens with an f-number of 2.5 and a large offset angle, recorded at 488 nm and read out at 633 nm. A nearly diffraction-limited spot size and an efficiency of >80% are measured.read more

Basics of Holography
TL;DR: This paper presents a meta-anatomy of holographic interferometry, a branch of imaging that combines Fourier transforms, computer-generated holograms, and other techniques, developed in the 1990s with applications in imaging and other applications.

Single and multiple element holographic devices for high-efficiency beam correction
TL;DR: In this article, a holographic element with a grating pattern that is impressed in the media of the element utilizing beams of electromagnetic energy of wavelength λ o is presented. But it is not suitable for the use of volume phase holograms.

Design of near-field holographic optical elements by grating matching.
TL;DR: It is shown that for designing near-field holograms, in which the optical images involved are close to the hologram aperture, the grating-matching technique is superior to the well-established aberration-balancing method introduced by Latta.

Coupled wave theory for thick hologram gratings
TL;DR: In this paper, a coupled wave analysis of the Bragg diffraction of light by thick hologram gratings is given, analogous to Phariseau's treatment of acoustic gratings and to the dynamical theory of X-ray diffraction.

Magnification and Third-Order Aberrations in Holography*
TL;DR: In this article, the authors derived formulas for angular, lateral, and longitudinal magnification in reconstructed images by holography (imaging by reconstructed wavefronts) and discussed conditions under which one or more of the aberration coefficients vanish, taking into account an off-axis angle of both reference and illuminating beam.

Nonparaxial Imaging, Magnification, and Aberration Properties in Holography*
TL;DR: In this paper, the imaging, magnification, and aberration properties of the images formed from holograms were extended to the non-paraxial case, which can be used to locate accurately the position of an image point in cases where the paraxial theory fails.

Computer-based analysis of hologram imagery and aberrations. I. Hologram types and their nonchromatic aberrations.
TL;DR: A close parallelism between the bending characteristics of lenses and the construction geometry of holograms is noted and illustrates the flexibility with which the aberrations of a hologram may be modified by changes in the recording geometry.
