液晶可编程相位调制器（PPM）用作三维超高分辨率光学相干断层扫描（UHR OCT）的自适应光学系统中的校正装置。研究了即使使用多色光时 PPM 校正高阶像差的可行性，显示出未来临床应用的潜力。通过高达 25,000 次 A 扫描/秒和高分辨率获得活体视网膜的体积 UHR OCT，可实现视网膜特征的可视化，这些特征可能对应于外部限制膜上的感光器终端条组。 (c) 2005 Elsevier Ltd. 保留所有权利。
A liquid crystal programmable phase modulator (PPM) is used as correcting device in an adaptive optics system for three-dimensional ultrahigh-resolution optical coherence tomography (UHR OCT). The feasibility of the PPM to correct high order aberrations even when using polychromatic light is studied, showing potential for future clinical use. Volumetric UHR OCT of the living retina, obtained with up 25,000 A-scans/s and high resolution enables visualization of retinal features that might correspond to groups of terminal bars of photoreceptors at the external limiting membrane.
