the birefringence for light propagating along vprop, the difference of the two refractive indices, and the polarisation axes of the fast and the slow wave; MATLAB’s birefringence

Syntax

n, pMin, pMax = rI.birefringence(vprop)

At the propagation directions.

n, pMin, pMax = rI.birefringence()

A function on the sphere and two axis fields.

Description

Light entering an anisotropic crystal along vprop splits into two waves polarised perpendicular to each other and to vprop, the fast one of the lower and the slow one of the higher refractive index. At a list of directions the differences are an array and the axes lists of axes; without a direction the difference is a function of the propagation direction and the axes are axis fields. MATLAB’s fourth and fifth outputs, the two indices nMin and nMax, are not returned.

Input

`rI`	refractiveIndexTensor
`vprop`	vector3d or Miller, the propagation directions in the frame of rI

Output

`n`	the birefringence nMax - nMin, or an S2Fun of the propagation direction
`pMin`	the polarisation axis of the lower index, the fast wave, or an axis field
`pMax`	the polarisation axis of the higher index, the slow wave, or an axis field
