Efficient and compact space invariant fanout holographic optical elements have been fabricated by combining the flexibility in design of computer-generated holograms with the versatility of conventional interferometric holography in dichromated gelatin. Effects of K-ratio variation and the phase distortion in the reconstruction fidelity are discussed. In addition, various preprocessing and postprocessing techniques have been employed to increase the optical damage threshold of these components to well over 100 W cm−2.
