Abstract:
The theory, design, and performance of a simple polarization calibrator based upon the polarization of specularly reflected light are presented and discussed. A formula is derived for the Rubenson degree of polarization of specularly reflected light in terms of the angle of incidence and the refractive index (real) of the material of the reflector. Criteria are presented for the design of an optimal diaphragm to minimize the depolarizing effects of light that has undergone a single internal reflection inside the body of the reflector.

Biasing of P-N Junction
In equilibrium, no external voltage is applied across the p-n junction. The depletion region is formed at the junction interface due to the diffusion of carriers, which leaves behind charged dopants, acceptors on the p-side, and donors on the n-side. These immobile charges create an electric field that prevents further diffusion of carriers. The related energy band...
