Method and apparatus for rapidly evaluating digital data processing parameters

An apparatus for real-time simulation of digital information which can be applied to holography including:

• an acquisition device configured to acquire 3-D measurement data;
• a processor configured to calculate a first two-dimensional array of sums of said 3-D measurement data, wherein each of said 3-D measurement data is directly raised to a power K.sub.1 to yield a quantity and adding a constant amount to said quantity to yield said first array of sums, wherein said constant amount is related to a noise value;
• a sum buffer configured to store said first array of sums;
• said processor configured to apply an inverse power function to said first array of sums to yield a second array;
• a display device configured to display said second array;
• and,
• a maximum value register configured to store a maximum value of said first array, wherein said processor is further configured to determine said maximum value and scale said second array by said maximum value to yield a normalized array, and said display device is configured to display said normalized array.
