Our work on the theory of phase contrast imaging  will appear in Physical Review Letters this week.

The theory was developed by Ebube Ilo-Okeke, and treats for the first time phase contrast imaging at the single shot level.  Past works treated the problem as a continuous measurement.

One interesting statistic: according to searching the APS database, this is the first paper in PRL since 1986 with a Nigerian affiliation.  The last one prior to our work was

Above: Schematic of the phase contrast imaging setup.  Light illuminates the BEC from the left and produces a phase shift in the light.  This is interfered with light that does not go through the BEC, to produce the measurement result.
