There was a similar technique discussed in a Ted Talk using femto-photography, which had an animation showing how it was done for an ELI5[0]. The talk contains references future technology to see around corners. This article may have been inspired by the talk, but it certainly makes it much more available for the rest of us. [0]: [VIDEO]
