This is a novel imaging technique from MIT that allows the capture and visualisation of light travelling through a scene in 'real time' captured at an effective rate of a trillion frames per second.
Individual photon packets and wave fronts are actually being captured with exposure times of around 2 pico seconds !
Examples of fruit being illuminated with a laser here and general explanation

However the technique is not straightforward (but simple to understand) and currently lends itself to static laboratory scenes.
So not so good for the astroimagers ! but amazing what technology and the human mind can achieve.
