We demonstrate two real-time, read-write holographic projectors of video images based on photorefractive materials. A photorefractive crystal holographically records multiple, angularly multiplexed 2D images. By sequentially reconstructing each pre-recorded image a holographic video is created. In first setup the 2D image of an LCD screen is holographicaly recorded in a photorefractive LiNbO3 crystal. In the second setup the Fourier transform of the LCD screen is recoded in the crystal. A detailed comparison of the two setups along with a number of videos is provided. The Fourier transform recording is superior in image quality compared to the direct image recording.
