Depolarization \De*po`lar*i*za"tion\, n. [Cf. F.
d['e]polarisation.]
The act of depriving of polarity, or the result of such
action; reduction to an unpolarized condition.
[1913 Webster]
{Depolarization of light} (Opt.), a change in the plane of
polarization of rays, especially by a crystalline medium,
such that the light which had been extinguished by the
analyzer reappears as if the polarization had been
anulled. The word is inappropriate, as the ray does not
return to the unpolarized condition.
[1913 Webster]
