We present a non-contact method of determining temperature change in a lithium niobate crystal. The technique has the advantage of being simple to implement and offers a precision at least as good as conventional temperature measurement methods over large ranges (∼ 200 K). A novel application of this technique involves measuring temperature in different regions of the crystal simultaneously, which could be useful for determining stresses and heat diffusion parameters. The technique could be successfully applied to monitor crystal temperature for thermal fixing of holograms or related applications.
