Paper Abstract

This paper discusses on holographic imaging based on six lateral phase derivatives. Six lateral derivatives are generated by a high-resolution reflection mode holographic grating that is designed in a “kite” configuration. The integration of the derivative yields the phase and the optical thickness. Demonstration of the proposed approach is carried out for the case of the analysis of the supersonic flow of a small vertical jet, 5.56mm in diameter.
