Abstract
The effects of phase and amplitude errors on the dynamic range in the images obtained by reconstruction by both the conventional method and by a new enhancement method are examined. It is shown that the dynamic range in enhancement imagery is little affected by phase errors. It is also shown that, if the width of the strong image is aperture-limited, the dynamic range in conventional holographic imagery increases as N in terms of intensity, where N is the number of sampling points. This increase continues until N is large enough so that the image width is no longer aperture-limited.
