Abstract
Some systems described herein include a frequency dependent phase plate for generating multiple phase-contrast images of a sample, each from a different frequency range of light, each phase-contrast image for frequency range of light formed from light diffracted by the sample interfered with undiffracted light that has a frequency-dependent baseline relative phase shift from the phase plate. In some embodiments, the multiple phase-contrast images may be used to generate a quantitative phase image of a sample. The phase-contrast images or the produced quantitative phase image may have sufficient contrast for label-free auto-segmentation of cell bodies and nuclei.
