Abstract
We explain that it is possible in principle to detect a change in light transmittance and phase shift of transparent materials without exposing even a single photon on them. Based on such interaction-free measurement, novel rewritable optical memories can be constructed with a photo-sensitive medium. In this case, even if the stored data are vulnerable to light, they can be read out without (or, at least a reduced) data impairment, because there is no (or, at least a reduced) interaction between the photon and the medium. We also discuss the effect of two system imperfections, the system loss and the low quantum efficiency of photon detectors, when such memories are to be implemented.
