  We report an experimental demonstration of a nonclassical imaging mechanism
with super-resolving power beyond the Rayleigh limit. When the classical image
is completely blurred out due to the use of a small imaging lens, by taking
advantage of the intensity fluctuation correlation of thermal light, the
demonstrated camera recovered the image of the resolution testing gauge. This
method could be adapted to long distance imaging, such as satellite imaging,
which requires large diameter camera lenses to achieve high image resolution.
