Talbot moire method for measurement of refractive index and density of liquid

For measurement of refractive index, density and temperature of liquid, according to the Talbot effect, a Talbot moire method and a Talbot moire deflectometer,which is an optical set-up of image formation by lensless system are presented. Their basic principle, technique and the moire fringe patterns are also described and given. This set- up is very convenient,economical,simple and easy to obtain the moire fringe with high quality. Thus, it may be commonly used for measurement of physical and chemical parameters of phase objects.
