Paper Abstract

Major environmental problems all over the world require immediate action. Often a quantitative observation of the environmental effects on natural or man-made systems is asked for. Useful information about the object is collected in the speckle fields produced by scattered coherent light. Object changes are detected by correlation of corresponding speckle fields. Optical methods are employed for this task: holography, holographic interferometry, double- exposure speckle photography, speckle correlation, or electronic speckle pattern interferometry. Modifications of these techniques are adapted to on-site and real-time applications in environmental diagnostics. Practical results are presented in examples from the study of plants and the monitoring of climatic effects on cultural stone monuments.
