Statistical properties of mutual intensity with finite measurement time

The accuracy with which the amplitude and phase of an interference fringe can be measured in quasi-thermal light is limited by the finite integration time used. The statistical errors expected in such a measurement are derived analytically, and their dependence on measurement time, the coherence time of the light, and the complex coherence factor are explored. An example illustrating the utility of the results is presented.

Analogy between Holography and Interferometric Image Formation*

An analogy is drawn between holographic imaging with coherent light and interferometric imaging with incoherent light. By means of a spatially offset incoherent reference source, the amplitude and phase of the complex coherence factor of an incoherent object may be encoded as amplitude and phase modulations of a function derived from classical visibility measurements. This imaging technique shares several properties with holography, including the ability to image through a distorting medium and the ability to form three-dimensional images.
