Abstract:   (919 Views)

Moiré technique has many applications in optical wavefront measurement and determination of small changes in e.g. tiny length transitions or atmospheric fluctuations. Based on the Moiré technique, this paper reports a new method to measure changes in wavelength of the incident light. This method is based on the chromatic aberration of the lens used for magnification of the Moiré pattern. Experimental results obtained from three different sources with 450 , 532 and 632 nm wavelengths show the total Moiré patterns rotation of about 29.3o which is in good agreement with calculated resultss.

Keywords: Moiré technique, wavelength alteration, chromatic aberration, Moiré pattern.
