Imaging properties of a second-order hologram (SOH), i.e., a thin off-axis hologram with the amplitude transmittance involving expansion terms up to quadratic in exposure, are investigated. It is shown that by reading such a hologram by a partial or distorted object image it is possible to obtain a complex conjugate associative response, i.e., reconstruct a conjugate object image. The advantages of a SOH over the linearly recorded 2-D and even 3-D ghost- image holograms are in that it is capable of reproducing the original intensity distribution in the conjugate image and permits a reciprocal associative reconstruction of noninterfering complicated wave fronts. Also discussed are the associative properties of volume SOH.
