Digital　holography　is　widely　used　as　a　high　resolution　metrological　technique　in　many　domains.　As　a　coherent　imaging　method,　the　speckle　noise　is　inherent　in　the　system　and　degrades　image　quality　and　optical　resolution.　An　improved　fiber-space-hybrid　lensless　Fourier-transform　digital　holography　system　is　proposed.　Multiple　holograms　are　recorded　with　different　oblique　illumination.　All　hologram　are　reconstructed　individually　using　the　same　program　and　each　reconstructed　image　has　a　different　speckle　pattern.　The　oblique　illumination　system　is　optimized　by　an　automatic　two　dimensional　scanning　of　the　fiber　tip.　Thus　only　a　limited　illumination　area　of　light　spot　is　demanded.　By　averaging　the　reconstructed　images,　the　speckle　noise　of　the　reconstructed　image　is　reduced.　We　demonstrate　the　effectiveness　of　the　technique　experimentally.　The　proposed　system　is　convenient　and　practical.　It　can　lead　to　a　high　quality　result　automatically.
