A method for digital holographic microtomography comprises (a) providing at least one wavefront controlling device for driving a sample to be rotated and/or an incident beam scanning the sample, (b) utilizing a digital holographic access unit for recording the transmitted or reflected wavefronts of the sample, (c) utilizing a digital holography reconstructing method for reconstructing the transmitted or reflected wavefronts of the sample, and (d) utilizing a tomographic reconstruction approach for reconstructing three dimensional image information of the sample.
