Paper Abstract

Short exposure measurements of the atmospheric lateral coherence length (r0) are shown to be biased by random apodization at the entrance apertures of a Hartmann r0 measurement device. A model for random apodization cells is mathematically developed and the errors in angle-of-arrival fluctuation measurements and r0 computations are investigated. Compensation for apodization bias is investigated, and some compensating measurement devices are proposed. The influence of instrumental and computational errors on angle-of-arrival fluctuation measurement errors is also discussed.
