Resolution capability test and phase contrast imaging of rPMT at a meter-scale object-to-screen distance. a The normalized SPS image of a transmissive USAF 1951 resolution target at an object-to-screen distance of ZOS = 1019.0 mm, with an exposure time of 150 ms. b Single-shot reconstruction from (a). c Detailed region (the elements in Group 7 of the USAF 1951 resolution target) cropped from (b). d, e The green and red line profiles correspond to the marks in (c) for the line pairs of Group 7 Element 4 with a line width of 2.76 μm. f The single-shot experimental result for a random-matrix encoding transmissive mask with an element size of 9.26 μm. g, h Two detailed regions cropped from (f). i The retrieved single-shot phase contrast image through rPMT using a phase object generated by a reflective-mode phase-only SLM. Here, the line widths of the resolution target image loaded into the phase-only SLM are not identical with those of a standard USAF 1951 target. Refer to Supplementary Fig. S6 for further details. j, k Another two retrieved phase contrast images
