Abstract
Using pulsed Sodium laser beacon,the exploration experiment of the return light measurement is carried out. The wavefront of Sodium laser beacon of one pulse and the wavefront of natural star of the same direction are measured using two Shack-Hartmann wavefront sensors simultaneously. The results of experimental data analysis show that the return photons numbers received of Shack-Hartmann wavefront sensor’s one subaperture are more than 200, and the intensity of Sodium laser beacon’s return light is even and steady. The signal-to-noise ratio of light spot distribution is about 3~5. The statistical variance of each order Zernike coefficient of Sodium laser beacon’s wavefront and natural star’s wavefront is consistent in the gross, and the pertinency of each order Zernike coefficient is well.
