The LC used in the proposed structure is an anisotropic material consisting of rod like molecules which are characterized by
ordinary index no and extraordinary index [n.sub.e].
Then, in the case of the
ordinary index, we obtain a number of discrete values [Y.sub.B], plotted in function of the degree of crystallinity [x.sub.c].
By recording on
ordinary index cards the names of all patients with abnormal blood tests, we speed their treatment and prevent unnecessarily repeating tests.
