In this paper we are presenting a simple model of an optical tomographic memory. Tomography, which is usually used to obtain the information from the natural object (like human body), is used here to retrieve the information previously artifically stored in a volume media. Memory readout is done in incoherent white light, by detecting the intensity of the radiation transmitted in various directions through the memory.
