Abstract

We have demonstrated that the intermodulation light, normally found in off-axis holograms of real (diffuse) objects, can be suppressed to any desired degree by a scanned illumination recording technique. This is accomplished by illuminating the object only over a very small region (spot) at a given time. An improvement in speed and reconstruction efficiency over the spot-scan recording is obtained by a line-scan technique. For three-dimensional objects, an additional problem arises due to the finite aperture of the hologram, and a double-scan technique is described to obviate this difficulty. Experimental results are presented for all three methods.
