论文摘要
我们考虑在天生近似的假设下,通过光学衍射断层扫描重建三维对象的成像问题。我们的重点在于刚性物体在声学或光学力下执行不规则,时间依赖的旋转。在这项研究中,我们比较了如果i)进行重建算法,即已知复合价值波的二维图像,或II)只有这些图像的强度(绝对值)才能测量,在许多实际设置中,这种情况就是这种情况。后一种相位回答问题可以通过使用电视正则化的混合输入输出方案来解决全面的方法。
We consider the imaging problem of the reconstruction of a three-dimensional object via optical diffraction tomography under the assumptions of the Born approximation. Our focus lies in the situation that a rigid object performs an irregular, time-dependent rotation under acoustical or optical forces. In this study, we compare reconstruction algorithms in case i) that two-dimensional images of the complex-valued wave are known, or ii) that only the intensity (absolute value) of these images can be measured, which is the case in many practical setups. The latter phase-retrieval problem can be solved by an all-at-once approach based utilizing a hybrid input-output scheme with TV regularization.
