Fig. 5: Static and dynamic quantitative phase imaging of biological cells.

The reconstructed phase distributions of biological cells COS7 (a) and Hs68 (b). The dotted-line boxes “i–iv” are enlarged to inset for visualization. c Several frames for the quantitative phase map over time of moving NIH3T3 cells. A cross-section plot along the white dotted line is included as an inset. The phase unwrapping algorithm was applied.
