- pygrin.pygrin.ABCD(n_0, pitch, length, z)¶
ABCD matrix for meridonal ray propagation.
n_0 – index of refraction at center of grin lens [unitless]
pitch – pitch or period of the lens [unitless]
length – axial length of the lens [mm]
z – distance within lens from front surface [mm]
float – the ABCD matrix for meridonal ray propagation [radians]
