We present a method of enhancing the diffraction efficiency of a hologram by placing it inside a resonant optical cavity. The diffraction efficiency improves on account of the multiple passes that the incident light undergoes inside the optical cavity.

Optics Letters, 2012
A new technique, referred to as Stokes holography, is proposed and experimentally demonstrated for controlled synthesis of generalized Stokes parameters in 3D space using Stokes fringes. Stokes fringes are polarization fringes which permit to record and reconstruct complete wavefront.

It is altogether fitting that in this commemorative conference, we celebrate the one application of holography that would have pleased Dennis Gabor the most, its contribution to culture and education. Among the many uses of holography, the most frequently lauded are display, interferometry, HOE, and a myriad of other technical applications.

The utility of holography for many applications will depend upon the quality and resolution of the images reconstructed from the hologram. In this paper some of the practical limitations encountered in the'attainment of high resolution images from holograms are investigated on a theoretical and experimental basis.

Holograms were made that recorded on a single piece of film an entire study case in three dimensions. Other applications of holography in dentistry are discussed. On a qualitative basis, it appears that holography has potential application in many fields of dentistry.

The Research News article “Two versions of holography vie to show atoms in 3D” by Steve Nadis ([3 May, p. 650][1]) discusses exciting new developments in x-ray analysis at atomic resolution ([1][2]). Is it accurate, however, to describe these methods as holography?

This paper discusses some aspects of holographic display techniques pertinent for museum applications. In particular, it revises the features and requirements for three-dimensional (3D) holographic displays, examines the practical use of holographic interferometry as an effective tool for non-destructive inspection of museum items, discusses ...

Journal of the Optical Society of America A, 1985
A novel coherent imaging method analogous to electronic differential amplification is described and analyzed. The method is well suited to highlighting local changes in the optical properties of a dynamic object whose more prominent details are largely static. The object may be examined either in transmitted light or in reflected light.

The conditions for magnetic hologram formation are reviewed and an analysis is given to explain some of the unique polarization effects seen on reconstruction, with both the Faraday and polar Kerr effect reconstructions treated. Experiments are presented which illustrate the features and storage potentials of magnetic holography.
