Outline of Final Research Achievements

Computer holography including electro-holography and digital holography has a potential to be a next-generation three-dimensional technology for imaging and measurement. The most important problem is speedup of the calculating process. We have studied it from three approaches. First, we developed FPGA (Field Programmable Gate Array) board for holography calculation, whose scale is larger than that in the market. The performance of the board is 100 times faster than a personal computer. Furthermore, the parallel system consisting of several boards showed the computing speed improvement in proportion to the number of boards. Secondly, we applied GPU (Graphics Processing Unit) calculation to various algorithms and succeeded in speedup for them. Thirdly, we suggested several methods for speedup and/or high resolution. We published these results in more than 40 articles.
