Quantum ghost imaging was explored by use of a chaotic laser light source, a photon effcient charged coupled
device (CCD) camera, a stencil mask, a photon bucket detector, and computer processing. We investigated and
successfully achieved quantum ghost imaging of the stencil letters ARL from macroscopic time integration scales
of 1ms to 10ms. Importantly, quantum ghost images were obtained from photons which did not interact with the
letter object. In addition to the timescale effect on ghost imaging we investigated the role of speckle spatial size
in resolving images. Results are presented from our investigations of these components of the time and space
correlations of photons emanating from chaotic laser light and ending in both the photon bucket detector arm
and the CCD arm. Important applications for quantum imaging and quantum ghost imaging are also discussed.
