Plexiglass aberrators In this experiment we wanted to test the ability of the system to compensate for high order aberrations. We placed a plexiglass sheet halfway between the transmitter and the receiver.

The theory of holomorphic dynamical systems is a subject of increasing interest in mathematics, both for its challenging problems and for its connections with other branches of pure and applied mathematics. A holomorphic dynamical system is the datum of a complex variety and a holomorphic object (such as a self-map or a vector field) acting on it.
