Snapshot projection optical tomography
Published 2019-06-11Version 1
We present a new plenoptic microscopy configuration consisting of an objective lens and a micro-lens array (MLA), which is used as a tube lens. The new system that we named as snapshot projection optical tomography (SPOT) can directly record the projection images corresponding with different viewing angles, and it contrasts with existing plenoptic imaging, which uses an MLA as a Shack-Hartmann sensor. For a theoretical analysis, we extended a 3-D forward imaging model for high-NA telecentric system. We also acquired the image of a 6-$\mu$m fluorescence bead, which clearly showed the optical-sectioning capability of SPOT.
