The chromatic sensitivity of holographic optical elements for use in optical interconnect systems is quantified using an entropy merit function. The influence of broad-band illumination on axial irradiance and intensity is studied showing that the best imaging point obtained with…

A novel method for the characterization of the processing of both absorption and phase holograms is proposed. Differently from the previous models, the square root of the diffraction efficiency of the processed hologram was directly related to the amplitude of…

Optical densities before bleaching and final Lin curves of planewave phase holograms recorded in Agfa—Gevaert 8E75HD emulsions were measured for various combinations of developers (AAC, Pyrogallol and Catechol) and bleaching agents (R-9 and EDTA). To characterize the processing, the square…

Silver halide sensitized gelatin (SHSG) is an interesting technique for the production of holographic optical elements. It combines the high sensitivity of photographic emulsions with the well-known low scattering and high diffraction efficiency corresponding to dichromated gelatin. In this paper…

Photopolymers are studied as holographic recording materials for recording computer-generated phase holograms. The recording was performed using a holographic copying process, in which the master is produced by means of a high resolution graphic device. To our knowledge it is…

An article analysing the law on corrupt fixing in sport., This sports law paper looks at betting related match-fixing and its variant spot-fixing. Proposals to curb fixing are discussed as are recent laws and moves at self regulation in the…

This article will offer an analysis of Andrej Zulawski’s Possession (1981) with the work of Luce Irigaray to suggest female desire both is and can create monsters. Through the parabolic configuration and ultimate collapse of the transcendental mystical with the…

This article proposes an ontology-based topological representation of remote-sensing images. Semantics, especially related to the topological relationships between the objects represented, are not explicit in remote-sensing images and this fact limits spatial analysis. Our aim is to provide an explicit…

The electroreflectance (ER) technique has been applied to the study of the electrooxidation of some simple amino acids (glycine, serine and alanine) on a Pt(111) surface in acid medium. A different behaviour in the (1:R)(#R:#E) response as a function of

Over the last 30 years, strength and power training has been a major issue for, coaches, athletes and researchers. Unfortunately, despite the increasing professionalization of coaches and athletes, there is little research data concerning performance in top athletes. In fact,…
