Demonstration of single pixel computational ghost imaging with pseudo-randomly patterned illumination from a liquid crystal display

An experiment demonstrating computational ghost imaging with structured illumination and a single-pixel detector has been performed. Our experimental setup utilized a general computer for generating pseudo-random patterns on the liquid crystal display screen to illuminate a partially-transmissive object. With this similar true thermal light source, this object is imaged. The formula of the computational ghost imaging with this light source has been derived. The experimental results agree with the theoretical analysis. The liquid crystal display screen is more applicable for ghost imaging with ordinary incoherent light as the source of illumination.
