Now we have two holograms with filenames: IMAGE2 and IMAGE3. Let's
    display them side by side as they will be simultaneously photographed
    for production of the beam-combining optics of a photonic transistor.
    Note the differences between the holograms. One projects an image of
    a dot at the focus. The other also projects a dot at that same spot.
    However the light arriving  one side is 180 degrees out of phase from
    the light which arrives from the other side.  

      This occurs, because HIMAGE.COM has made white (transparent in the  
    functioning hologram,) every pixel that produces constructive inter- 
    ference at the focus from the left side. However by changing the phase 
    of the right side input, HIMAGE.COM has made white, every pixel which 
    will now send light out of phase with every pixel from the first  
    hologram. Thus, when both hologram inputs are on, DESTRUCTIVE INTER- 
    FERENCE takes place at the focus, and the LIGHT IS DISPERSED ELSEWHERE 
    ON THE OUTPUT SQUARE. 
 
      The display syntax is: DIMAGE IMAGE2 IMAGE3. The one on the left.
    is the first one displayed.
