摘要：

In　this　paper,　imaging　characteristics　with　different　light　sources　based　on　volume　holographic　imaging　system　are　researched.　The　volume　holographic　lens　as　imaging　lens　is　recorded　in　the　2-mm-thick　LiNbO3:Fe:Cu　crystal　at　wavelength　of　532　nm.　The　imaging　characteristics　of　the　imaging　system　are　researched　at　the　reading　wavelength　of　532　nm　and　640　nm.　The　results　show　that　the　depth　resolution　of　volume　holographic　imaging　system　is　different　when　different　reading　wavelengthes　are　used.　Axial　selectivity　is　more　sensitive　when　the　red　light　is　used　as　the　reading　light.　The　imaging　features　of　monochromatic　light　source　and　broadband　light　source　are　compared.　Experimental　results　show　that　using　broadband　light　source　can　obtained　more　transveres　information　of　the　object.
