SPATIAL COHERENCE OF LIGHT EMITTED FROM OPTIC FIBER

The mathmatic model of light emitted from optic fiber as source is given, and physical characteristics of the light is discussed. The relationsghip between V number of optic fiber,and coherent length & mean intensity extension of light emitted from fiber with a Gaussian intensity distribution is obtained in the Franhauf diffraction domain. The comparasion between this theory and diffraction field of incoherent source agrees with Van Cittert-Zernike law is made. The experimental result conincides with theory.
