16-step phase-shifting fringe images

These are the 16-step phase-shift fringe images and five gray code fringe images that we collected and applied to the experiment. To facilitate the comparison experiments, we also supplement the average intensity images.
In order to better compare the experimental results, we collected the images of no target, horizontal discontinuous target and continuous target respectively, so that the results can better reflect all kinds of situations, so as to make the results more extensive and illustrative.
