Paper Abstract

MooSci is a linear array of photodiodes that measures time varying intensities of light reflected from the Moon, lunar scintillation. The covariance between all possible pairs of photodiodes can be used to reconstruct the ground layer turbulence profile from the ground up to a maximum height roughly determined by the distance between the furthest pair of detectors. This technique of profile restoration will be used for site testing at various locations. This paper describes the design of a lunar scintillometer and preliminary results from Las Campanas Peak.
