Some explanations about concepts of fringes of interferogram and coherence

Dear all, The phase difference can have contributions from five different sources: Δφflat is called flat Earth phase which is the phase contribution due to the earth curvature.  Δφelevation is the topographic contribution to the interferometric phase.  Δφdisplacement is the surface deformation contribution to the interferometric phase.  Δφatmosphere is the atmospheric contribution to the interferometric phase. It is introduced due to the atmospheric humidity, temperature and pressur…
