| dc.description.abstract | 在本篇研究中，我們利用了頂角為165度的軸稜鏡(Axicon lens)產生貝索光束，並結合掃頻式光學同調斷層顯微術來提升橫向解析度。根據我們實驗的結果，在景深1.29mm的範圍內我們量測到的橫向解析度光點大小為~5微米，其靈敏度約為~94dB。 | zh_TW |
| dc.description.abstract | In this study, a swept source optical coherence tomography (SS-OCT) system that profits from the enhanced lateral resolution performance of Bessel beam illumination was developed. Using an axicon lens with a top angle of 165 degree, nearly constant lateral resolution of ~ 5 micro meter over a focusing depth of at least 1.29 mm is demonstrated with an invariant sensitivity of ~ 94 dB. | en_US |
