Abstract
Typically, tomographic reconstruction of dynamic 3D samples is limited by sample movement speed and illumination scanning speed. However, using the six-pack holography technique that we have developed, 6 off-axis holograms of different illumination angles can be acquired in a single camera exposure, without sacrificing individual image resolution or field of view, and without requiring sample sparsity. Using these 6 holograms we reconstruct the 3D refractive index tomogram of a dynamic sample from each video frame using the optical diffraction tomography algorithm. We demonstrate our technique experimentally on flowing microbeads and swimming microalgae.
