| Outline of Final Research Achievements |
i) Paraxial solutions for curved computer-generated holograms were derived using asymptotic analysis. The results are verified using simulated experiments and fabrication of a real cylindrical hologram is in process. Another analytic solution based on Bessel function was developed. The results showed faster computation and lesser memory requirements and was reported as journal publication
ii) The developed solutions required hundreds of giga-pixels to be processed and hence a parallel computing algorithm was developed on a 16-node pc cluster. The developed method could achieve 20-times improvement in computation time compared to conventional methods .
iii) A non-parallel version of the developed algorithm was re-used for digital holography imaging application. The results were published as journal article. The developed methods will be useful for curved holographic display developments.
