Results under different photon flux levels at D/r₀ = 6. (a) Initial uncorrected wavefront. (b) The corresponding ideal focal-plane image of (a), with an SR of 0.11. (c)–(g) From left to right: simulated focal-plane images with photon noise and readout noise, corrected wavefronts, and corrected focal-plane images. From top to bottom: correction results with photon numbers of 1000, 2000, 3000, 4000, and 5000, respectively. The corresponding SR values of the corrected images are 0.83, 0.83, 0.83, 0.83, and 0.84, respectively. (h) Horizontal lineout of focal-plane images.
