Fig. 3: The high-speed zoom imaging of fluorescent microsphere.
From: Compressive confocal microscopy imaging at the single-photon level with ultra-low sampling ratios

a Experimental results of fluorescent microsphere in our 4× and 1× zoom imaging modes with different sampling ratios of 0.2%, 0.1%, 0.05%, and 0.03%. The orange curves in the inset are the intensity profile along the corresponding orange line trace. The corresponding scale bar is 20 μm. b The curves of peak signal-to-noise ratio (PSNR) and structural similarity index measure (SSIM) with different sampling ratios.
