Hologram aberrations are introduced in the reconstructed wavefronts when the reconstruction geometry and/or the reconstruction wavelength are different from that used in construction. Interference patterns of the hologram aberrations can be observed by real-time or double-exposure holographic interferometry.
This paper describes the method for obtaining the interference patterns of the hologram aberrations and shows the experimental results. The results are compared with those calculated by the aberration theory for holograms. There is good agreement between theory and experimental results. Some unfamiliar interference patterns of the combined third-order aberrations and a fifth-order aberration were obtained by this method.
