I have seen this before. Nice talk by the way! I don't think this is exactly what it claims to be. The result is that but the procedure is possibly a bit different methinks. What they may be doing is "range gating". Send out a pulse of light and catch the returning reflected light at slightly different times and in this time the light they catch is that which is reflected from farther and farther locations. I think this is so but I could be wrong. It is not like they have a camera that does what we come to believe a motion picture or video camera does in terms of recording so many frames a second. At least I don't think so. Can anyone here enlighten me? Comments?
