Abstract

The types of shadow noise in interferogram are accounted for and the methods of shadow correction are introduced briefly.This paper puts forward the minimal value method in each template block and the manual criterion method to correct additive noise and the Gaussian blur method to correct multiplicative noise in the spatial field.The methods are analyzed theoretically and applied to process the interferogram to be proved to be feasible and get the satisfied result.
