Recent progress in tomographic diffractive microscopy

摘要

Tomographic diffractive microscopy (TDM), also known as phase tomography, synthetic aperture microscopy... is becoming a more and more mature technique. It is an extension of holographic microscopy, with controlled conditions of illumination. Several views of the sample are numerically combined to reconstruct a 3-D image. Commercial implementations are even already available, but there are still challenges to be addressed to improve the method. We present possible approaches to further speed up acquisitions, simplify reconstructions and/or improve sensitivity/contrast.
