Computation of image differences is a key operation in computational imaging. We use time-of-flight sensors to perform this operation in a single shot, and discover some remarkable features.

Many real-world surfaces are covered in fine scratches that diffract light in colorful ways. Our model seamlessly transitions between ray optics and wave optics to recreate this intricate effect.
