Double refraction, also called birefringence, an optical property in which a single ray of unpolarized light entering an anisotropic medium is split into two rays, each traveling in a different direction. ... The Figure shows the phenomenon of double refraction through a calcite crystal.
What is double refraction in uniaxial crystals?
Light traveling through such an anisotropic medium can exhibit double refraction or birefringence, in which an unpolarized incident light ray splits into two polarized rays with mutually perpendicular planes of vibration. ...
Why does double refraction occur?
Light passing through a surface at an inclination allows the slowing of that light to change the direction of travel, yielding refraction. ... This is double refraction caused by the birefringence. If the light enters normal to the prism face, each vibration travels at a different velocity, but no refraction occurs.
