| 中文摘要 | 為了在傅氏域光學同調斷層掃描中消除鏡像,我們發明了一套節省計算時間的新方法,於這消除鏡像法中,我們利用實像和鏡像有相反的相位差來區分這兩部份影像,在合理的近似假設下,藉由求得兩條方程式之解,我們可以得到實像的訊號。本文章中我們說明理論背景、平均的影像品質和疊代法的過程,也比較我們的消除鏡像法結果和現今一般廣泛使用的BM技術,結果發現我們的消除鏡像法需要的計算時間比BM技術來的短。 |
| 英文摘要 | The theory and experimental results of a computation time-saving mirror image suppression method in Fourier-domain optical coherence tomography, which utilizes the property of reversed system phase shift between the real and mirror images, for differentiating one from the other are demonstrated. By solving a set of two equations based on a reasonable approximation, the real image signal can be obtained. The theoretical backgrounds and the improved real image quality of the average and iteration procedures in this method are particularly illustrated. It is found that when a process procedure of two iterations is used, the mirror image suppression quality based on our method can be higher than that obtained from the BM-scan technique. The computation time of our method is significantly shorter than that of the BM-scan technique. |
