Rezumat:
We report the measurement of pyroelectric field in LiNbO3 by introducing a new method, based on optical interferometry. The pyroelectric coefficient of the congruent LiNbO3 crystals has been determined by this method and the value obtained for it, similar to 95 mu C/(m(2).K), is consistent with previous results reported in literature, obtained by other methods.
