Paraxial Ray
Paraxial Ray : Originally defined for an optical system with a symmetrical axis of rotation. A light ray near this axis and which has only a small inclination to the axis is called a paraxial ray. In seismic ray theory it is defined as a ray generated by perturbing the source position or take-off direction of a central ray. The dynamic ray equation governs the properties of the paraxial ray. See Chapter 9 in Lee et al. (2002)
