1. Multiplexed Digital Holography incorporating Speckle Correlation
Abstract : In manufacturing industry there is a high demand for on line quality control to minimize the risk of incorrectly produced objects. Conventional contact measurement methods are usually slow and invasive, meaning that they cannot be used for soft materials and for complex shapes without influencing the controlled parts. READ MORE

2. Combined Digital Holography and Speckle Correlation for Rapid Shape Evaluation
Abstract : In manufacturing industry there is a high demand for on line quality control to minimize the risk of incorrectly produced objects. Conventional contact measurement methods are usually slow and invasive, meaning that they cannot be used for soft materials and for complex shapes without influencing thecontrolled parts. READ MORE

3. Combined speckle interferometry and speckle correlation for non-destructive testing
Abstract : When a sample is studied during loading in a tensile test machine, the sample is often exposed to rigid body motions during loading at the same time as it deforms due to tension. Therefore, the small deformation field is hard, or impossible, to measure when it is overlaid by a large motion. READ MORE

4. Digital speckle photography and digital holography for the study of transparent media
Abstract : In the fields of combustion and fluid mechanics, temperature- and density fields are of interest to measure. Optical measurement methods may be used to study such transparent media. Flames, gases and liquids are examples of transparent media, often called phase objects in an optical context. READ MORE

5. White light and x-ray digital speckle photography
Abstract : The goals of this work were not only to develop new measuring techniques, but also to validate their performance, in terms of accuracy, spatial resolution, etc., by performing carefully chosen experiments. The measuring techniques were also to be applicable to industrial problems in production, control or product development. READ MORE
