Abstract

We measured the time series of irradiance from a diverged He-Ne laser using 3- and 7-mm receiver aperture sizes that simulated the day-adapted and night-adapted human pupil. The propagation range was 1 km at a height of 2 m above flat grassland. The data are within the saturation-of-scintillation regime wherein the irradiance variance decreases with further increases of propagation distance and refractive turbulence strength.
