An interference scheme is proposed for studying the spatial entanglement of twin photons. By Fourier transformation, phase and frequency matching takes the form of spatial and temporal entanglement, respectively. We use a description in space and time to show the analogy between the spatial and temporal entanglement of twin photons.
