We present a method of fractional Fourier transform digital holographic recording by setting an extended Lohmann I-type optical setup in the object arm of a typical off-axis digital holographic recording system. In the experiment, the resolution and the field of view for the reconstructed images of a fractional Fourier transform holograms and an image plane hologram are investigated. When the lens focal length meets a certain condition, the reconstruction imaging resolution of fractional Fourier transform holograms is higher than that of conventional image-plane holograms. The reconstruction results demonstrate that the reconstructed images of the fractional Fourier transform holograms have the higher imaging resolution when the fractional order p is closer to 1.
