Holography, with all of its truly remarkable properties, is yet 
to leave the laboratory. Two great steps in the right direction, however, 
were made with the development of the laser and the improved method of 
reconstruction by Leith and Upatnicks in 1963. Since that time, considerable 
effort has been expended in melding together its capabilities and the needs 
of optical information processing in a practical manner. 
Thus, we see that startling developments have been made both in 
electronic image scanning and in optical processing that have yet to be fully 
explored to determine their full potential in image enhancement and other 
processing steps leading to improvements in the speed, accuracy, and complete- 
ness of photo interpretation and possibly to the eventual automation of certain 
functions. 
Therefore, it appears desirable to thoroughly investigate both 
these techniques, pick out the inherent advantages of each, and marry them 
to provide a state-of-the-art system that would significantly aid the photo 
interpreter. 
The result may be an interpretive system that would present 
possibly both the original imagery and a second enhanced field that would 
draw the attention of the interpreter to selected images and flag certain 
areas as being potentially fruitful. Time consuming detailed search, therefore, 
would be reduced considerably. 
The decision as to the identity of the target and its significance, 
however, must be the interpreter's. After all, he is still the best learning 
machine and integrator developed to date and it is unlikely that any organization 
can develop one that is any better.
