Unequivocal Cardiac Phase Sorting From Alternating Ramp-And Pulse-Illuminated Microscopy Image Sequences

In vivo microscopy is an important tool to study developing organs such as the heart of the zebrafish embryo but is often limited by slow image frame acquisition speed. While collections of still images of the beating heart at arbitrary phases can be sorte ...

Temporal resolution doubling in fluorescence light-sheet microscopy via a hue-encoded shutter and regularization

Michael Stefan Daniel Liebling, Christian Jaques

Studying dynamic biological processes, such as heart development and function in zebrafish embryos, often relies on multi-channel fluorescence labeling to distinguish multiple anatomical features, yet also demands high frame rates to capture rapid cell mot ...

Aliasing mitigation in optical microscopy of dynamic biological samples by use of temporally modulated color illumination and a standard RGB camera

Michael Stefan Daniel Liebling, Christian Jaques

Significance: Despite recent developments in microscopy, temporal aliasing can arise when imaging dynamic samples. Modern sampling frameworks, such as generalized sampling, mitigate aliasing but require measurement of temporally overlapping and potentially ...

Active illumination and computational Methods for Temporal and Spectral Super-Resolution Microscopy

Christian Jaques

Light microscopy is a tool of paramount importance for biologists and has been constantly improved for the past four centuries. Despite many recent developments, microscopy techniques still require improvement, especially to reach better temporal and spect ...

Temporal Super-Resolution Microscopy Using a Hue-Encoded Shutter

Sylvain Calinon, Michael Stefan Daniel Liebling, Emmanuel Pignat, Christian Jaques

Limited time-resolution in microscopy is an obstacle to many biological studies. Despite recent advances in hardware, digital cameras have limited operation modes that constrain frame-rate, integration time, and color sensing patterns. In this paper, we pr ...
