我们提出了一种可调输出频率滤波器(TOF)算法来重建的对象从噪声的实验数据下的低功率部分相干照明,如LED,通过散射介质成像时。在迭代算法中,我们采用高斯函数与不同的滤波器窗口在迭代过程的不同阶段,以减少腐败的实验噪声,以寻找一个全局最小的重建。与传统的迭代相位恢复算法相比,我们证明了所提出的TOF算法在实验噪声存在下实现了一致和可靠的重建。此外,由于滤波器仅应用于对象外部的区域,因此在重建中保留了空间分辨率和独特特征。实验结果证明了该方法的可行性。
We present a tunable output-frequency filter (TOF) algorithm to reconstruct the object from noisy experimental data under low-power partially coherent illumination, such as LED, when imaging through scattering media. In the iterative algorithm, we employ Gaussian functions with different filter windows at different stages of iteration process to reduce corruption from experimental noise to search for a global minimum in the reconstruction. In comparison with the conventional iterative phase retrieval algorithm, we demonstrate that the proposed TOF algorithm achieves consistent and reliable reconstruction in the presence of experimental noise. Moreover, the spatial resolution and distinctive features are retained in the reconstruction since the filter is applied only to the region outside the object. The feasibility of the proposed method is proved by experimental results.
