Processing of holographic AgBr films studied by x-ray fluorescence analysis
Abstract:
The feasibility of using x-ray fluorescence techniques to determine the concentrations of silver, bromine, and iodine in silver halogenide holographic films is studied. A small apparatus employing a 30-mCi (57)Co radioactive source and a germanium photon detector is described. AgBr films were exposed to different amounts of light and subjected to several types of chemical processing, and their silver and halogen contents were investigated. In addition, the relationship between the concentration of absorbing silver in the emulsion and its optical density was determined.

Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...
X-ray Diffraction of Biological Samples
According to Bragg's law, when X-rays strike the sample positioned on a stage, the rays are scattered by the electron clouds around the sample atoms. The X-ray diffraction or scattering is caused by constructive interference of the X-ray waves that reflect off the internal crystal...
