Dynamic Tomographic Phase Microscopy by Double Six-Pack Holography
No full textThree-dimensional
(3D) optical imaging of rapidly moving biological
cells is difficult to achieve as such samples cannot be scanned over
time. Here, we present a dynamic scan-free optical tomography approach
for stain-free 3D imaging of biological cells using our new double
six-pack tomography technique, whereby 12 off-axis holograms are captured
in a single camera exposure without sacrificing resolution or field
of view. The proposed system illuminates the sample from 12 angles
simultaneously, and 3D refractive index (RI) tomograms are reconstructed
from each recorded video frame of the dynamic sample. The technique
is verified experimentally by recording flowing silica beads, 3 μm
in diameter, with the resulting tomogram RI accuracy being 98.5%.
A live swimming sperm cell is also imaged, and dynamic 3D imaging
results for both beads and sperm cell are presented. The proposed
technique represents a 12-fold increase in dynamic holographic data
for tomography
