Abstract

The wavenumber nonlinearity leads to blurred reconstructed images in spectral-domain optical coherence tomography (SDOCT). In this work, a wavenumber-linearisation method without calibration devices is presented, based on the fact that the difference between the phases of adjacent peak and valley points is equal to $π$ . The theoretical model is derived, and the efficacy of the method was proven by acquiring SDOCT data from TiO₂ phantom and zebrafish. The results exhibit the superior performance of our method. Compared with the linear phase-based method, the resolution could be improved at least a factor of 2. Compared with the polynomial fitting method, the resolution could also be improved by nearly half.

用于光谱域光学相干断层扫描的无校准波长线性化装置。

在光谱域光学相干断层成像（SDOCT）中，波数非线性会导致重建图像模糊。在这项工作中，基于相邻峰谷点的相位差等于 π $\pi $ 这一事实，提出了一种无需校准设备的文波数线性化方法。推导出了理论模型，并通过获取二氧化钛模型和斑马鱼的 SDOCT 数据证明了该方法的有效性。结果表明我们的方法性能优越。与基于线性相位的方法相比，分辨率至少提高了 2 倍；与多项式拟合方法相比，分辨率也提高了近一半。

期刊介绍： The Journal of Microscopy is the oldest journal dedicated to the science of microscopy and the only peer-reviewed publication of the Royal Microscopical Society. It publishes papers that report on the very latest developments in microscopy such as advances in microscopy techniques or novel areas of application. The Journal does not seek to publish routine applications of microscopy or specimen preparation even though the submission may otherwise have a high scientific merit. The scope covers research in the physical and biological sciences and covers imaging methods using light, electrons, X-rays and other radiations as well as atomic force and near field techniques. Interdisciplinary research is welcome. Papers pertaining to microscopy are also welcomed on optical theory, spectroscopy, novel specimen preparation and manipulation methods and image recording, processing and analysis including dynamic analysis of living specimens. Publication types include full papers, hot topic fast tracked communications and review articles. Authors considering submitting a review article should contact the editorial office first.
