Photorefractive crystals such as iron-doped lithium niobate can be useful recording materials in holographic interferometry. These crystals are self-developing, erasable and reusable, and sensitive to the recording laser light only. As such they are extremely convenient for routine interferometry applications. In this paper, experiments in interferometry using iron-doped lithium niobate crystals for recording the holograms are discussed. The results presented include double-exposure holographic interferometry with cw and pulsed lasers, holographic subtraction interferometry, and real-time interferometry with photorefractive reference holograms. Example applications such as visualization of aerodynamic flow fields, heat transfer patterns, and acoustic fields are presented.
