Microradiography and Absorption Microscopy
The techniques of radiography are as old as the knowledge of X-rays, and of course are widely used in medicine, biological research and inspection of engineering components. A lack of high-intensity tunable sources has meant that its use on a microstructural level for materials has been very limited so far. However, we now have synchrotron radiation sources. As Lang has pointed out , almost any camera that will take diffraction topographs will take high-resolution radiographs, so the instrumentation will be available. The purposes of this short chapter are to summarise the experimental techniques for obtaining microradiographs, to state the conditions determining contrast and resolution and to speculate on possible applications in the study of crystals and crystal growth.
