  We propose a computational ghost imaging scheme using customized pink noise
speckle pattern illumination. By modulating the spatial frequency amplitude of
the speckles, we generate speckle patterns with a significant positive spatial
correlation. We experimentally reconstruct images using our synthesized speckle
patterns in the presence of a variety of noise sources and pattern distortion
and shown it is robust to noise interference. The results are compared with the
use of standard white noise speckle patterns. We show that our method gives
good image qualities under different noise interference situations while the
traditional way fails. The proposed scheme promises potential applications in
underwater, dynamic, and moving target computational ghost imaging.
