27.6: Limits of Resolution- The Rayleigh Criterion
WebThe maximum angle from the axis of the fiber at which the light ray may enter the fiber so that it will propagate in core by total internal reflection. Hence, this maximum angle is … WebThis means that to be guided through an optic fibre, a light ray must enter the core with an angle less than a particular angle called the acceptance angle of the fibre.
