title = "Phase correction in low coherence diffraction phase microscopy using the optical transfer function",
abstract = "In this work, we experimentally determine the transfer function of our recently reported epi-illumination white light diffraction phase microscopy (epi-wDPM) system. The transfer function identifies how the low frequencies below k0NAcon are modified due to the limited spatial coherence and how the high frequencies above k0NAobj are affected due to the limited objective numerical aperture. Using this transfer function, we perform deconvolution to remove the halo and obtain proper quantitative phase measurements without the need for excessive spatial filtering. The wDPM and epi-wDPM systems are now capable of obtaining halo-free images with proper topography at much higher speeds.",
