Summary on Grant Application Form |
|
The RA will construct suitable optoelectronic control systems to synchronise the camera, Pockels cell and computer. Software will be written to carry out the windowed Fourier transform data analysis. The reliability of temporal phase unwrapping using various spatial and temporal window dimensions will be investigated. The RA will use constant velocity translation or rotation stages to test the relative performance of (a) the windowed FFT algorithm and (b) the phase shift algorithm. The complete system will then be tested on vibrating plates and dynamically loaded crack specimens. The RA will also carry out work on the SLM adaptive optics, characterising the properties of a SVGA resultion device. Experiments will be carried out to determine the device's fringe contrast, and to investigate its noise reduction capabilities.
