The necessity of studying the nature of the propagation of the maximum of the laser radiation pattern in the Anderson differential cell is substantiated. A new technique has been developed for conducting these studies, which takes into account all factors when constructing the trajectory of the maximum laser radiation in the cuvette, as well as outside it (up to the sensor of the photodiode line, on which the radiation is recorded). For the first time, an equation was derived to study the change in the nature of the propagation trajectory of the maximum of laser radiation in the Anderson cell, and beyond it, depending on its various parameters, the values of the refractive indices of the reference ns and the liquid medium under study, nm. The results of checking the reliability of the developed equation are presented. For the first time, a 12th degree polynomial was obtained for Anderson's differential cell with respect to the refractive index of the medium under study to obtain an analytical solution of the developed equation. This solution will provide additional information about the physics of the processes under consideration and the relationships between different quantities. Keywords: laser radiation, refraction, liquid, refractive index, Anderson cell, spread trajectory, equation, polynomial.

“…The optical fiber refractive index sensor has aroused great interest in chemical and biological applications due to its advantages: compact size, high sensitivity, electromagnetic interference, and real-time sensing [1,2]. To date, various optical fiber refractive index sensors have been proposed and developed to achieve high sensitivity based on tilted fiber grating [3][4][5], fiber Bragg grating [6], the Fabry-Perot interferometer [7][8][9], the Mach-Zehnder interferometer [10][11][12], the D-shaped surface plasmon resonance [13], and the fluid-filled photonic crystal fiber coupler [14,15]. However, the aforementioned refractive index sensors are single-point sensors, which could not be used for the real-time monitoring of solution diffusion or the reaction process in safety checking of marine ships and quality inspection in chemical industry applications.…”

A distributed optical fiber refractive index sensor based on etched Ge-doped SMF in optical frequency domain reflection (OFDR) was proposed and demonstrated. The etched Ge-doped SMF was obtained by only using wet-etching, i.e., hydrofluoric acid solution. The distributed refractive index sensing is achieved by measuring the spectral shift of the local RBS spectra using OFDR. The sensing length of 10 cm and the spatial resolution of 5.25 mm are achieved in the experiment. The refractive index sensing range is as wide as 1.33–1.44 refractive index units (RIU), where the average sensitivity was about 757 GHz/RIU. Moreover, the maximum sensitivity of 2396.9 GHZ/RIU is obtained between 1.43 and 1.44 RIU.
