Ground truth images obtained via AFM are shown in panels a, f, k, and p. b, g, l, and q show the standard open aperture (OA) CARS image, where CARS signal (involving no reference beam) from all detector pixels is summed. c, h, m, and r show confocal (single on-axis pixel) CARS images, as a proxy for the resolution obtained by pixel reassignment. d, i, n, and s show images from pixels located at 1 Airy unit from the optical axis, and e, j, o, and t show images from pixels located at 1.3 Airy units. Scalebar = 1 μm.
