What is Phase Shift in Dielectric Reflection about?

The phase shifts in external dielectric reflection were analyzed as a function of the incident angle. The contrast of the interference fringes formed between the incident and the reflected beams was considered. For the parallel mode the phase shift disappears between 450 and the Brewster angle. Experimental results are shown which demonstrate the contrast inversion in this region. ## Introduction In the description of interferometers by amplitude division, the light reflected from an optically denser medium is considered to undergo a phase shift of half of a wavelength. As empirical grounds for this, Lloyd's experiment in the case of grazing incidence and Newton's rings in the case of normal incidence are usually given. The theoretical explanation is given by Fresnel's relations, which are obtained by solving the boundary conditions that must be satisfied by the electric and magnetic fields at the surface of discontinuity. The deduction of these relations is treated in many books on classical optics, such as Sommerfeld, 1 Born and Wolf, 2 and Hecht and Zajac. 3 However, the treatment of this subject there is incomplete if one wishes to calculate the contrast and the width of the fr
