We compared the performance of several deformable mirrors and deformable lenses as regard their capability of correcting static and dynamic aberrations both in open- and closed- loop. These tests highlighted notable differences between the devices as regards the performance in different cases, as well as their ease to use.

The combination of Digital holography and acoustofluidics provides distinct advantages. While a transparent piezo assures optical investigation through the microchannel, we employ holographic imaging to assess the acoustic manipulation and to calibrate bulk acoustic waves.

The volume of ice particles generated in a freezing column is estimated using a multi-view interferometric out-of-focus imaging set-up. The influence of possible errors in the 3D-reconstruction process of particles is evaluated.

We design a deep neural network where the known physical forward operator is explicitly embedded and apply it to phase retrieval under low photon conditions to achieve better performance over the end-to-end approach.

Nature's limits are precious: they often reveal uncertainty products connecting coherence, resolution, precision, channel capacity... So we can bargain with nature for "optimal" 3D sensors with novel features or just better precision, resolution, speed.
