Abstract

When an obstacle blocks a partially coherent beam, after a certain distance this beam can return to the previous pattern before the obstacle, without any signature of the obstacle, thanks to the self-reconfiguration effect. Exploring this effect, a useful application was envisaged: the possibility to see through different layers of a biological sample. For this, we use the mesentery of a rat, a translucent material covered by cell walls and irrigated with small blood vessels inside.
