Abstract

A novel optical configuration in holographic interferometry (HI) is proposed for measuring object tilt and in-plane displacement. In this holographic interferometer a photorefractive crystal (PRC) is used as holographic recording material, which can be reusable and do not require additional processing (development, fixing, etc.), and the procedure of real-time interferometry is adopted. Theoretical analysis and preliminary experimental results are given.
