Through the miniaturization of the distance between transmitter and detection fiber to < 600 µm, the light can also permeate high disperse phase fractions of up to 60 %. Due to the measurement setup, both transmission and scattering effects can be found in the resulting signal. The possible mathematical description of the resulting nonlinear measured curve using a simplified model follows.de660 Chemische VerfahrenstechnikFaseroptische RückstreusensorenHochgefüllte DispersionenInline‐ÜberwachungPhotometrieFiber‐optic backscattering sensorsHighly filled dispersionsInline monitoringPhotometryArticle2020-11-091522-2640
