Dr. Oren Raz came up with an idea for a new way to circumvent the phase reconstruction problem: to combine two ultra-fast laser flashes and measure them together, so that the combination between the two would act as a hologram

The shape of the flash - how to measure a very fast phenomenon using a much slower detector
