With Gaussian intensity distribution or normal random intensity distribution, the correction of Zernike aberrations by a 37-element curvature adaptive optics system was simulated, and compared to the correction with uniform intensity distribution. In the case of Gaussian intensity distribution, the nonuniform of intensity brings about some influence into the correction of Zernike aberrations. The influence on Zernike aberrations with non-zero curvature is more serious than that to Zernike aberrations with zero curvature. In the case of normal random intensity distribution, the influence on Zernike aberrations is small. The correction of Zernike aberrations with zero curvature is more accurate than that for the non-zero curvature aberrations. The results indicate that the 37-element curvature adaptive optics system can correct low order Zernike aberrations when the nonuniform intensity is not very serious.
