From: 3D-printed biological cell phantom for testing 3D quantitative phase imaging systems
(a,b) SEM images of the phantom slices. 1 - the resolution test in the Y direction; 2 - the spheres representing the nucleoli; 3 - the resolution test in the Z direction; 4 - a thin wall separating internal structures from the immersion medium. (c,d) Cross-sections of the 3D RI distribution of the phantom showing final arrangement of the features along the Z axis. Phantom sits on a 3D printed support - 70 μm long cylinder to offset the structure from the surface of the optical fiber (not visible). The scale bars are 10 μm long.
