Nonlinear Effects in Holography

The ideal photographic material in holography would have a linear relationship between amplitude transmittance and exposure. Here we study the case where this relationship can be described instead by a polynomial. This nonlinearity in reconstruction gives rise to some extra images, autocorrelations, autoconvolutions, and ambiguity functions of the object, which may be found superposed on normal images, or spatially separated both laterally and in depth.
