Take the 2-minute tour ×  This TED talk suggests that we can now
watch as a beam of light propagates through a bottle filled with
water. My question is: can we use this new technology to perhaps
'see' the photon as it makes its way to the detector screen in
the double slit experiment? What implications can femto-
photography have on the single/double-slit experiment and
physics in general?  share|improve this question  1 Answer 1  In
the video, Dr Raskar describes the process a little more in-
depth. To create the femto-photography videos, his team actually
takes extremely short exposures of a light pulse travelling
through a medium (e.g. a bottle filled with water) at very
precisely synchronised time intervals, so they are basically
shooting packets of light at the target one-by-one very many
times and taking a picture each time with another time offset.
In effect, you're making a measurement each time, registering
the photon's position in space. Its wave function collapses,
resulting in a random position in
