   Hi all,   
      
   Among the different kinds of merit function construction for illumination   
   optics,ray-aiming is one of them that is widely used for decreasing the   
   computational effort. Does anybody know to construct such kind of merit   
   function? -or any reference?   
      
   Thanks,
