Light-sheet microscopy excels in fast whole-organ acquisitions either in clarified mouse brains or intrinsically transparent zebrafish larva. Here, we present our technical and optical solutions for microscope automation including autofocusing, Bessel beams and prospective gating.

Precise 3D point localization is increasingly important in microscopy, but algorithms break down when PSFs overlap. We adapt the CLEAN algorithm from astronomical imaging to enable MLE localization of high-density datasets.

We found a full analytical solution to Schrodinger equation on a simple enclosed surface: a regular tetrahedron. The time evolution of a wavefunction on it is then completely equivalent to an optical Talbot effect.
