| Abstract: | The statistical properties of the complex amplitude and the intensity of the interferometric field in holographic interferometry are derived by means of the statistical method. It is hown that the complex amplitude is a zero-mean circular complex Gaussian random process, the intensity obeys a hegative exponential proba-biliby density function and the ensemble average of the intensity represents the deformation information. |
