Gates: a period of time in the recording stage, so you are not seeing the 
fringes moving because it is a complete time-averaged result. 
Ek: Yes, and it is important to distinguish between the object motion and 
the motion of the fringes, that occur with this type of evaluation. 
The object motion is recorded as a time-average in the hologram, and this 
average is stationary in time. But during reconstruction the fringes move 
due to fringe parallax and the motion of the reconstructed beam.

Discussion of the above paper 
Danko: I would just like to make a comment that I think it is interesting 
that Dr. Ghosh has described a simple analytical plotter system that has a 
promising future, when compared to expensive analytical systems. 
  
Ghosh: I believe in that future. It is a simple analytical system in a 
way, but made out of scraps out of the already available simple analogue 
system.
