This paper shows that visible-light ptychography can be used to distinguish quantitatively between healthy and tumorous unstained cells. Advantages of ptychography in comparison to conventional phase-sensitive imaging techniques are highlighted. A novel procedure to automatically refocus ptychographic reconstructions is also presented, which improves quantitative analysis.
Similarly, Claus et al. REF show the use of visible-light ptychography to distinguish between healthy and tumorous unstained cells in a MATLAB implementation.
