Abstract
An apparatus and method for simulating atmospheric scintillation includes a scintillation disk and a motor for rotating the disk at a substantially high speed. The disk has a dense varied pattern of substantially small closely spaced holes. The holes have different sizes and are arranged with a spatial distribution that is gaussian in amplitude and poisson distributed in separation. The motor can spin the disk to produce desired temporal variations as energy from the energy source passes through the holes of the disk.
