11. 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

12. 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

13. Digital holographic interferometry in a disturbed environment
Abstract : Digital holographic interferometry is an optical measurement technique that is capable of measuring the movement/deformation of an object surface with extremely high accuracy, spatial resolution and temporal resolution. But, because it is very sensitive to disturbances, it is mostly used in well controlled laboratory environments. READ MORE

14. Time resolved digital holographic interferometry through disturbed phase objects
Abstract : Digital holographic interferometry is an optical measurement technique based on the work by Powell and Stetson in 1965. The basic principle of the method is that the whole light wave (both amplitude and phase) from an opaque surface or transparent object can be captured and stored using a single camera. READ MORE

15. Combination of optical methods for studies in combustion and wave propagation
Abstract : In this thesis, different optical methods were combined for studies of combustion processes in gases and transient wave propagation in plates and water. Pulsed TV holography was used in all these projects. READ MORE
