TL;DR: In this article, an exact formulation of the grating diffraction problem without approximations is presented, using a series of fundamental assumptions, which reduces to the various existing approximate theories in the appropriate limits.

TL;DR: In this article, the diffusion equation is solved in the low-order harmonic approximation, in order to describe the grating formation process in dry photopolymer materials, and the ratio between diffusion and polymerization rates is described.

Coupled wave description of the diffraction by zone plates with high aspect ratios
Jörg Maser,G. Schmahl +1 more
TL;DR: In this article, a coupled-wave description of zone plates with high aspect ratios is given, and the concept of optical thickness is used to consider the change in the diffraction properties of a high resolution micro zone plate with increasing radius.

Planar volume phase holograms formed in bleached photographic emulsions.
R. R. A. Syms,Laszlo Solymar +1 more
TL;DR: Volume phase holograms are formed by a standard process in commercially available photographic emulsion and an improved model is formulated, capable of analytic solution, taking into account phase and absorption modulation, a second harmonic in the grating profile and the appearance of some higher diffraction orders.

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.

Diffraction of a Plane Wave at a Sinusoidally Stratified Dielectric Grating
Abstract: The problem of diffraction at a sinusoidally stratified dielectric grating is treated. The analysis of the reconstruction process from a hologram formed in a “thick” photographic emulsion leads to this problem, but it may also occur in other areas. A rigorous solution of this problem is presented for both polarizations of the electric wave. The solution is evaluated numerically for values of the different parameters that are typical for holograms. It is shown that the amplitude of the diffracted light has a maximum if the light is incident at the Bragg angle, a feature already observed experimentally. Results are given for different values of the period as well as the thickness of the grating and for both polarizations.

The diffraction of light by high frequency sound waves. Part I
C. V. Raman,N. S. Nagendra Nath +1 more
TL;DR: In this paper, the authors developed the fundamental idea that the phenomenen of diffraction of light by high frequency sound waves depends on the corrugated nature of the transmitted wavefront of light, pointed out by the authors in their first paper.
