Well, if you a hardcoding-only POV-Ray nutcake (my ICQ nick is
pov-nut) you could  try using the SuperPatch to create a function for
an isosurface and use it as 1) an ithersection of two isosurfaces
situated closely to make the sheet and 2) a density pattern for a
scattering media in the sheet to do the fuzzy light effect you are
after.

Just a thought.
