Experimental results of image reconstruction with SWM. a: Original MAP image of a ring texture resolution chart; b: The processed MAP image of Fig. a; c: Horizontal profile along colored dashed-lines in a and b rendered with different colors; d: Vertical profile along colored dashed-lines in Figs. a and b; e: Image of vessels in the abdomen of a laboratory rat; f: Joint histogram comparison of different images; g-i: The above images of g-i are distorted images; the middle images are the corrected depth-coded images (processed images); the lower images of g-i are superimposed images between the original images and the processed images; white-arrows and rulers are utilized to mark obvious correction. Norm.: Normalized; ToF: Time of flight; Pro.: Processed; Ref.: Reference; Reg.: Registered; units: μm
