逆光谱光学相干层析成像(ISOCT)用于表征颗粒尺寸和浓度

Inverse spectroscopic optical coherence tomography (ISOCT) for characterization of particle size and concentration

James Hope, Matthew Goodwin, Frederique Vanholsbeeck

摘要:

逆光谱光学相干断层扫描(IS-OCT)方法将逆问题公式应用于采集的光谱,以估计深度分辨的样品特性。在目前的研究中,我们使用Lambert-Beer定律建模的时间-频率-分布和实现IS-OCT使用后向散射光谱从Mie理论计算,然后演示了在理想条件下的聚苯乙烯微球的算法。结果是显着的,因为该方法生成的浓度和散射颗粒的直径的深度相关的估计。

英文摘要:

Inverse spectroscopic optical coherence tomography (IS-OCT) methods apply inverse problem formulations to acquired spectra to estimate depth-resolved sample properties. In the current study, we modelled the time-frequency-distributions using Lambert-Beer law and implemented IS-OCT using backscattering spectra calculated from Mie theory, then demonstrated the algorithm on polystyrene microspheres under idealized conditions. The results are significant because the method generates depth dependent estimates of both the concentration and diameter of scattering particles.
