Multimode fiber optic sensors [PDF]
The Journal of the Acoustical Society of America, 1990 A theoretical approach useful in the design of multimode optical fiber sensors is described. An intensity distribution function is derived when assuming that a multimode optical fiber is illuminated by a light source that can be approximated by infinite uniangular beams carrying equal power.
