In　order　to　eliminate　the　fiber　drift　errors　in　a　frequency-scanning　fiber　interferometer,　we　propose　a　self　reference　frequency-scanning　fiber　interferometer　composed　of　two　fiber　Michelson　interferometers　sharing　common　optical　paths　of　fibers.　One　interferometer　defined　as　reference　interferometer　is　used　to　monitor　the　optical　path　length　drift　in　real　time　and　establish　a　measurement　fixed　origin.　The　other　is　used　as　a　measurement　interferometer　to　acquire　the　information　from　the　target.　Because　the　measured　optical　path　differences　of　the　reference　and　measurement　interferometers　by　frequency-scanning　interferometry　include　the　same　fiber　drift　errors,　the　errors　can　be　eliminated　by　subtraction　of　the　former　optical　path　difference　from　the　latter　optical　path　difference.　A　prototype　interferometer　was　developed　in　our　research,　and　experimental　results　demonstrate　its　robustness　and　stability.　(C)　2016　Elsevier　B.V.　All　rights　reserved.
