SYSTEM METRIC FOR HOLOGRAPHIC MEMORY-SYSTEMS

We introduce M/# as a metric for characterizing holographic memory sys tems. M/# is the constant of proportionality between diffraction effic iency and the number of holograms squared. Although M/# is a function of many variables in a holographic recording system, it carl ba measur ed rom the recording and erasure of a single hologram. We verify exper imentally that the diffraction efficiency of multiple holograms follow s the prediction of M/# measured from a single hologram. (C) 1996 Opti cal Society of America
