We propose a numerical wavefront manipulation method for synthesizing a new interference term from two digital holograms recorded using the same reference wavefront. The interference term of interest is synthesized indirectly, and its reconstructed image is unaffected by the reference wavefront used during hologram recording. We present experimental results of the indirect synthesis of the interference term corresponding to the lensless Fourier hologram using the Fresnel hologram.
