| Summary: | 碩士 === 國立臺灣師範大學 === 光電科技研究所 === 98 === In this study, we investigate the properties of parallel computing with graphics processing unit (GPU) and its application on off-axis digital holographic microscopy (DHM). First, we study the properties of parallel computing with graphics processing unit and compare the performance to the serial computing with central processing unit (CPU). And the parallel computing with graphics processing unit can be used to integrate a filter algorithm into the numerical reconstruction calculation to get a good-quality reconstructed image and reduce the calculation time. The digital holographic microscopy equipped with the graphics processing unit can also accelerate the phase unwrapping procedure for obtaining the three-dimensional profile of a specimen in real time. This work demonstrates that high-speed parallel computing of graphic processing unit in digital holographic microscopy has great potential to perform numerical reconstruction and phase unwrapping in real time. The analytical and experimental results are presented and discussed.
