Abstract
The issues of optimizing a fiber-optic time-of-flight optical turbidimeter are discussed and the conditions for its optimal operation with sensitivity being the optimization criterion, are determined for both conventional and distributed implementations. An optimization technique is proposed: for the usual case, expressions are obtained for the optimal relationship between the measurement time on the receiving fiber of the light signal emitted by the transmitting fiber, counted from the pulse start moment, and the distance between the transmitting and receiving fibers; for the distributed version of the implementation of the turbidimeter, the conditions for the extreme operation mode are determined. The technique can be applied in advanced water quality control systems.
