In this paper, an off-axis holographic lens with the focal length of about 70mm is recorded in the azobenzene liquid crystal polymer film (azo-LCP) by 532nm YbVO4 double-frequency lasers and is reconstructed by a 633nm He-Ne laser. The particularity and main advantage of the work consists in writing and reading out the hologram at the same place, without moving, post-exposure adjusting or chemical processing. The converging and imaging property of the holographic lens is measured and analyzed.
