Abstract: A fiber-optic sensor is formed from three optical fibers. The distal ends of the fibers are optically linked by bonding their cores and directing their ends to mirrors. A portion of one of the fibers near the bonded point is exposed directly to the fluid to be sensed. The transmission characteristics of this fiber, the signal fiber, is then affected by the chemical constituents of the fluid. Light directed into the proximal end of one of the other fibers, the input fiber, is split between the signal fiber and the remaining fiber, the reference fiber. The ratio of the light in the signal fiber to the light in the reference fiber provides an indication of the chemical constituents that minimizes errors introduced by factors such as bends in the fibers and temperature.
