Simulation result of moving nanorings by TCSRM. (a) Compressed image and reference image measured by two channels in TCSRM. (b) GT and TCSRM images for six consecutive frames. The moving trajectories of the nanorings are labeled with green lines. (c) Motion traces of the three nanorings in the whole scene from GT (lines) and reconstructed result by TCSRM (circles, squares, and rhombuses). (d) Radial intensity distributions of the nanorings along the white line in the reference, GT, and TCSRM images (Video 1, mp4, 845 KB [URL: https://doi.org/10.1117/1.AP.5.2.026003.s1]).

Experimental result of flowing fluorescent bead in microchannel by TCSRM. (a) Compressed and reference images recorded by two cameras. (b) Reconstructed images by TCSRM. The trajectory of the moving bead is marked with white dashed lines. (c) and (d) Intensity distributions of the fluorescent bead along the horizontal and vertical directions in the reference image and the first frame in TCSRM images (Video 2, mp4, 89.7 KB [URL: https://doi.org/10.1117/1.AP.5.2.026003.s2]).
