Abstract
AbstractWe 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 algorithm 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.
