3D display of a day 7-post in vitro fertilization bovine embryo. En face images at different depths from the top embryo surface (a) 25µm, (b) 75µm, (c) 150µm, (d) 225µm and (e) 300µm (all measured in air) at the beginning of the experiment, scale bar = 50µm. (f) cross section view over 500 µm in depth (measured in air), scale bar = 150 µm x 150 µm.
