首次将最大熵方法(MEM)应用于光谱域光学相干层析成像以提高轴向分辨率(AR)。MEM通过拟合来估计功率谱。对于M=70的优化洋葱，离散傅里叶变换(DFT)的AR为18.8微米，比峰宽提高了3倍。当M=70时，MEM的计算时间是DFT的20倍。然而，由于MEM的有效性取决于样本结构，因此在实际应用中还需要进一步的研究。(C)2007年美国光学学会。
For the first time we applied the maximum entropy method (MEM) to spectral domain optical coherence tomography to enhance axial resolution (AR). The MEM estimates the power spectrum by fitting. For an onion with optimization of M = 70, the AR of 18.8 mu m by discrete Fourier transform (DFT) was improved three times compared with peak widths. The calculation time by the MEM with M = 70 was 20 times longer than that of DFT. However, further studies are needed for practical applications, because the validity of the MEM depends on the sample structures. (c) 2007 Optical Society of America.
