Digital Spectroscopy of Piezoelectric Crystalline Media. Phase 1
Abstract
The report describes the development and application of a new method for measuring the anisotropic permittivities of piezoelectric materials which we call Digital Refractometry (or Digital Spectroscopy). We show that Fresnel's equations for anisotropic media reduce to very simple forms for an incident angle of 45 and we transform these equations to the Stokes parameters and the Mueller matrix. Fresnel's equations for anisotropic media have been cast in a very useful form for experimental measurement by Wooten. And, one form of Wooten's equations allows the ordinary and extraordinary refractive indices to be uniquely and separately determined. The experimental configuration for measuring the ordinary and extraordinary refractive indices is then described. In our experiments a dual beam approach was used to overcome the laser intensity fluctuations.
