英文摘要	an optical configuration for parallel two-step phase-shifting digital holographic microscopy (dhm) based on a grating pair is proposed for the purpose of real-time phase microscopy. orthogonally circularly polarized object and reference waves are diffracted twice by a pair of gratings, and two parallel copies for each beams come into being. combined with polarization elements, parallel two-step phase-shifting holograms are obtained. based on the proposed configuration, two schemes of dhm, i.e., slightly off-axis and on-axis dhm, have been implemented. the slightly off-axis dhm suppresses the dc term by subtracting the two phase-shifting holograms from each other, thus the requirement on the off-axis angle and sampling power of the ccd camera is reduced greatly. the on-axis dhm has the least requirement on the resolving power of the ccd camera, while it requires that the reference wave is premeasured and its intensity is no less than 2 times the maximal intensity of the object wave.
