Measurement of the Second Order Correlation Tensor
It is well known that the second order coherence functions are closely related to the visibility of the interference fringes produced in an interference experiment . There have been several attempts [2,3] to determine the diagonal components of the correlation tensor from such visibility measurements. However, no attempts have been made to determine all the components of the second order correlation tensor. In this paper we report the results of the visibility measurements which may be used to obtain the various components of the second order correlation tensor for a stationary, homogeneous and isotropic optical field.
