A joint transform correlator (JTC) is presented in this paper that utilizes a thin LiNbO3 crystal plate in the Fourier plane. The crystal plate shows the real-time dynamic photorefractive characteristics. We first report investigations on the planar grating properties of a thin Fe-LiNbO3 crystal plate and then demonstrate a new JTC system by this plate. The system has the capability of shift-invariance and real-time adaptive filtering.
