透過時域擬譜法模擬光學相位共軛法在散射介質的相關研究

Abstract

光學相位共軛 ( Optical Phase Conjugation ) 為非線性光學、生醫光學等相關領域中，研究光學散射的重要議題之一。本研究利用時域擬譜法 ( Pseudospectral time-domain, PSTD ) 模擬生物體內的光學相位共軛現象。主要研究的方向為模擬反向的共軛波在振幅以及相位改變的過程中會具有的不同特性，並且針對不同的張角以及光訊號分析。背景的生物體介質設定為鞏膜以及角膜細胞，本研究針對兩者差異以及上述的條件進行一系列的研究。

Optical phase conjugation is an important issue in nonlinear optics and biomedical optics. We employed the pseudospectral time-domain method (PSTD) in this study to simulate the optical phase conjugation phenomenon. The research aims to simulate the different features of the reverse conjugate wave by modifying amplitude and phase. Then focus on different divergence angles and light signals. Finally, set up the biological medium as sclera and cornea cells. This study conducted a series of simulations in both above cases.
