Lensless ghost imaging with fully spatially incoherent source is investigated theoretically and experimentally. The effects of positive and negative defocusing on lensless ghost imaging are studied by using classical optical theory and a fully spatially incoherent source. Based on the numerical calculation and experimental results, we find that the negative defocusing has a stronger influence on imaging resolution when compared with that from the positive defocusing. To explain this phenomenon, the analytical expression of point spread function with the positive and negative defocusing is presented.
