Measurement of the refractive index using the Talbot effect and a moire technique.
A method using the Talbot effect and a moire technique to measure the refractive index of transparent materials is described for a plane-parallel plate and a liquid. Experimental verification has been carried out. The method can measure both high and low refractive indices. An accuracy of 5 units to the fifth decimal place can be achieved.
