   My (limited) understanding of it is that in the case of the control loop with   
   a vibrating mirror, the control loop is about making slight adjustments   
   (increasing or decreasing) to the carrier frequency while the control loop   
   without a vibrating mirror    
   has to start from idle to a given frequency (that of the random phase shifts)   
   to compensate them which might be less "efficient"? (serious lack of formalism   
   here, lol)
