    Quantum temporal ghost imaging utilizes the timefrequency correlation of photon pairs to realize the image transmission over optical fiber link of 50km, which shows the potential applications in protocols of quantum communications. But the present schemes usually present poor imaging quality poor and low transmission speed, limiting the future application to some extent. In this paper, the scheme is considerably modified and a programmable optical filter is used to digitally set the information of the imaging object. Based on the modification, the twodimensional image is transmitted automatically in realtime. Experimental results demonstrate that both the imaging quality and rate are notably improved with the modified scheme, pushing the applications of quantum correlation imaging in the field of quantum communications.
