Description	To describe the optical characteristics of phase object the moiré deflectometry system can be used. A Talbot interferometer is constructed with two gratings placed in a collimated beam of light. The moiré fringes are generated by superimposing the self-imaged grating in Talbot plane with the second reference grating (of the some period or near the some period as the first one). If the phase object is placed on front of the first grating, the light deflected by the object yields the shifted Talbot images and the resultant moiré fringes show the change of the refractive index of the phase object. This method can be also used for measurement of the refractive index of lenses as well as liquids and gases showing self-focusing and self-defocusing effect. Computerized video-image than enables observation and evaluation of changes of moiré fringes practically in real-time. In comparison with other interferometric methods the advantages of the moiré deflectometry technique are its extreme experimental simpli To describe the optical characteristics of phase object the moiré deflectometry system can be used.
