  We propose and experimentally demonstrate a method of polarization-sensitive
quantitative phase imaging using two photo detectors. Instead of recording
wide-field interference patterns, finding the modulation patterns maximizing
focused intensities in terms of the polarization states enables
polarization-dependent quantitative phase imaging without the need for a
reference beam and an image sensor. The feasibility of the present method is
experimentally validated by reconstructing Jones matrices of various samples
including a polystyrene microsphere, a maize starch granule, and a rat retinal
nerve fiber layer. Since the present method is simple and sufficiently general,
we expect that it may offer solutions for quantitative phase imaging of
birefringent materials.
