We describe the procedures, principles and properties of self-referential holography (SRH) in which any reference beam is not required to record and readout holograms.To improve the readout quality of SRH, we performed the numerical simulations and investigated the recording and readout properties in detail. As a results, we could successfully achieve the drastically improvement of the readout quality by shifting the focal position and by using oversampled additional pattern.
