Abstract: The use of charge-coupled devices (CCDs) for imaging in digital shearography necessitates the knowledge of their electronic (signal-independent) noise level, as the visibility of fringes produced is dependent on this factor. A method based on measuring the experimental CCD noise variance to construct a linear equation system is presented. From the solution of this equation system, the electronic noise level of a particular CCD used for imaging can be determined. Evaluation of CCDs based on this noise factor allows the performance of each CCD used in digital shearography to be compared.
