Abstract
A geometrical-optics formulation is used to derive expressions for the angle-of-arrival variance produced when a retroreflector is illuminated and observed through the turbulent atmosphere. No fluctuations are observed when the retroreflector is illuminated by collimated or focused light. Light focused at a distance near twice the reflector range can produce large fluctuations, whereas diverging illumination tends to produce a variance that is less than that which would be observed on the transmitted beam at the reflector.
