Hello,   
      
   My group is currently working on a project (3D reconstruction) that needs   
   large amount of random dot projectors. Maybe I should say diffraction gratings   
   for random dots instead of projectors because we have already purchased some   
   laser diodes （830nm).   
      
   We are now looking for manufacturers who can design and produce these grating   
   in in large volume (150,000 - 500,000 pieces).   
      
   The Kinect's dot pattern shows a good example of what we need (something   
   similar is OK).   
      
   We are posting this topic seeking help or cooperation. We appreciate for   
   anyone who can give us some information on some potential manufacturers or   
   designers.   
      
   You can also contact with us directly via xchen@oakland.edu   
      
   Thanks a lot,
