When can we see micromotion? Experimental and theoretical analysis of the ChiSCAT scheme
Andrii Trelin, Jette Abel, Christian Rimmbach +3
We present an in-depth analysis of ChiSCAT, a recently introduced interferometric microscopy scheme to detect recurring micromotion events in cells. Experimentally, we demonstrate…

ChiSCAT: unsupervised learning of recurrent cellular micro-motion patterns from a chaotic speckle pattern
Andrii Trelin, Sophie Kussauer, Paul Weinbrenner +4
There is considerable evidence that action potentials are accompanied by "intrinsic optical signals", such as a nanometer-scale motion of the cell membrane. Here we present ChiSCAT…
