Query: Non-degenerate wavelength computational ghost imaging with thermal light   Non-degenerate wavelength computational ghost imaging with thermal light
source is studied theoretically and experimentally. The acquired computational
ghost images are of high quality when the wavelength of computed light is
different from the light detected by bucket detector. Compared to the necessary
light of short wavelength in previous ghost imaging, the use of longer
wavelength light is demonstrated to bring about ghost images with higher
spatial resolution, in strong atmospheric turbulence.
