The effect of dopant concentration in iron-doped lithium niobate (Fe:LiNbO 3 ) crystal plates on the diffraction efficiency and the recording time constant of the holographic grating was investigated. Results showed that the impurity doping concentration affects the grating diffraction efficiency and the temporal characteristics of the thin crystal plates. Two examples of optical image recognition with these crystal plates were demonstrated. Two different methods in these two cases of optimizing either the temporal response or the diffraction efficiency of the crystal were discussed.
