An experiment was conducted to measure the contribution of atmospheric scatter to the angular profile of received laser irradiance at the eye following outdoor propagation. A 15 W 532 nm laser was propagated over a 380 m outdoor range in San Antonio, Texas during summer 2014. A measurement technique was developed to determine an atmospheric scatter function, which was then compared to human eye scatter to assess the overall impact on laser eye dazzle. It was concluded that, for such short range laser engagements in atmospheres of good to moderate air quality, atmospheric scatter makes a negligible impact upon laser eye dazzle.
