WebIntroduction. The OBS is an optical sensor for measuring turbidity and suspended solids concentrations by detecting infra-red light scattered from suspended matter (see Figures 1A and 1B). The response of the OBS sensors strongly depends on the size, composition and shape of the suspended particles (see Figure 2). WebThe theory of backscattering in single-mode optical fibers is described through use of a correlation function for the refractive-index fluctuation in the fiber. A simple formula for the backscattered power is derived using two correlation functions for the Booker–Gordon and Gaussian models.
