Interference,　where　the　superposition　of　two　or　more　waves　resulting　in　a　new　wave　pattern,　has　been　considered　as　one　of　the　most　important　and　fundamental　physical　phenomenon.　In　optics,　the　statistical　properties　of　light　play　an　important　role　in　determining　the　outcome　of　most　optical　experiments　and　the　cross　correlation　between　the　fluctuating　fields　at　different　space　time　points,　known　as　the　optical　coherence　functions,　is　a　quantity　of　great　interest.　Due　to　the　fact　that　the　wave　equations　govern　propagation　of　optical　coherence,　it　can　be　envisaged　that　the　interference　phenomena　also　appear　in　the　format　of　the　optical　coherence　function.　Meanwhile,　the　study　of　propagation　and　superposition　of　optical　coherence　function　also　provides　theoretical　and　experimental　foundations　for　coherence　holography.　In　this　paper,　we　have　given　the　mathematical　expression　of　interference　of　the　optical　coherence　functions,　and　have　proposed　a　full-field　coherence　visualization　system　for　coherence　holographic　interferometry.　The　interference　of　two　optical　coherence　functions　has　been　experimentally　investigated　which　can　be　regarded　as　an　extension　of　Young＇s　double-slit　interferometer　for　optical　waves.　Some　interesting　phenomena,　such　as　missing　class　of　the　coherence　function　and　multiple-coherence　function　interference　are　demonstrated　for　the　first　time.
