it is already possible with existing devices - like night vision googles for example, where one kind of photons hit some electronic photon capturing device, CCD sensor for example, and the CCD would generate electric current which can be used to generate another kind of photons on the screen.
Similar, in principle, information transfer is happening in this experiment too - see my other comment https://news.ycombinator.com/item?id=8235764 - image carrying beam physically affects crystal (it is IR after all, and it does heat up the crystal and thus the distribution of the heating up of the crystal is also affected by the object being imaged) where photons used to generate final image are formed.
