Fig. 3: Experimental results of imaging biological sample using the micro-ring sensor array with parallel interrogation.

Scale bars: 1 mm. a Imaging result of a piece of leaf buried inside 5-mm thick tissue-mimicking phantoms using the micro-ring sensor array. b imaging result of the same leaf using only one micro-ring sensor. c, d Enlarged view of the area enclosed in white dashed boxes in (a and b). e One-dimensional profiles along the white lines in the reconstructed images in (a and b) are plotted in red and blue, respectively. f Reconstructed image of the head of a 3-month-old adult zebrafish using the micro-ring sensor array. g Reconstructed image of the tail of a 3-month-old adult zebrafish using the micro-ring sensor array, (h) Whole-body imaging of a zebrafish 7 days post-fertilization using the micro-ring sensor array. DA dorsal aorta, CV cardinal vein, DLAV dorsal longitudinal anastomotic vessel. i Whole-body imaging of a zebrafish 20 days post-fertilization using the micro-ring sensor array. SC spinal column, DF dorsal fin, AF anal fin.
