  A simple and robust experiment demonstrating computational ghost imaging with
structured illumination and a single-pixel detector has been performed. Our
experimental setup utilizes a general computer for generating pseudo-randomly
patterns on the liquid crystal display screen to illuminate a
partially-transmissive object. With an incoherent light source, this object is
imaged. The effects of light source, light path, and the number of measurements
on the reconstruction quality of the object are discussed both theoretically
and experimentally. The realization of computational ghost imaging with
computer liquid crystal display is a further setup toward the practical
application of ghost imaging with ordinary incoherent light.
