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
