   About 17 years ago I first learned about "3M louvered film"
   [3]http://solutions.3m.com/wps/portal/3M/en_US/AutomotiveDisplay/Soluti
   ons/Products/ReflectionControlFilms/ , an extruded sheet product with
   tiny "louvers" of black plastic, separating clear plastic blocks.  The
   purpose of this product was to block light passing through at a
   greater-than-desired angle. (the limiting angle can be varied by buying
   different models of material.)  If a sheet was placed over a license
   plate, with the 'louvers' horizontal, the plate cannot be read if the
   camera is viewing the scene at a too-high elevation.  (alternatively,
   or in addition, a second sheet of vertical louvers can be placed in
   front or back of the horizontal louvers, which would prevent the plate
   from being read from a camera at a too-high azimuth:   the an angle, on
   the horizontal plane, from the side of the road).
