Abstract
In this paper we derive the underlying equations for real time holographic interferometry through selfdiffraction, and demonstrate experimentally on how to employ the different Bragg and non-Bragg diffraction orders to perform one shot determination of the phase deformation, or equivalently, the depth information of a deformed object. We also show that the various diffracted orders may be phase shifted with respect to each other with a constant phase shift which depends on the phase mismatch and the length of the recording material. This technique can therefore have an obvious advantage over traditional phase-shifting holography due to the elimination of the piezo-shifted mirror (inducing the different phase shifts) which limits the traditional technique to slow deformations.
