“…Also, based on previous experiments with similar sensors, it can be concluded that changes over time in the process of absorption of evaporated substances are qualitatively the same for all three color curves and to some extent reflect changes in the degree of optical transmittance [19][20][21]. We accept these changes as an analytical criterion for the action of alcohols.…”

“…The principle of operation of an optical sensor lies in the process of registering an information signal from the source of radiation that has passed through the active medium to the photodetector [10,16,17,18]. In our case, the information signal is the wavelength [1,2,3].…”

“…These LC materials are characterized by the presence of a spiral supramolecular structure. Works [16,17,18] present the results of using a CLC active medium as an optical sensor of biological substances. Therefore, it is relevant to determine the concentration of flavonoids in alcohol solutions.…”

In order to solve the problems associated with the express registration of the presence of biologically active substances in callus biomass, we propose the use of cholesteric liquid crystal (CLC) with a spiral structure as a material of a sensitive element of optical sensor of flavonoids. Cholesteric liquid crystal BLO62 is proposed to use as a sensitive element. Spectral characteristics of alcohol solutions of flavonoids (20%, 40%, 70% and 90%) were obtained. The interaction of CLC with quercetin was analyzed. The scheme of the primary information signal converter is developed in which the current from the photodetector is transmitted to the developed signal converter. The device is implemented with the common use Atmega 328 microcontroller manufactured by Atmel. Speciality of this structural scheme is its flexibility and versatility, which makes it easy to reconfigure the parameters of the firmware for the registration of various types of investigated mediums.

“…Another example where accurate calculation of transients, phase and amplitude of oscillations in currentcarrying circuits is required are the primary devices of measuring systems. Thus, highly sensitive optical sensors are promising for qualitative and quantitative analysis of harmful substances, including biochemical substances [6][7][8]. The combination of numerical and analytical methods can increase the efficiency of calculations performed to model real systems [9] and their practical improvement.…”

The article considers the physical processes associated with the propagation of electromagnetic oscillations in a long line, the size of which is the same or slightly greater than the length of the electromagnetic wave (not more than ten times). As a research method, the differential-symbolic method is used, which is applied to the modified equation of the telegraph line. The boundary conditions for the two-point problem as well as additional parameters that are coefficients for the first derivatives in terms of coordinate and time in comparison with the classical equation of the telegraph line are considered as parameters for controlling the process of propagation of electromagnetic oscillations. Based on the differential-symbolic method, the boundary conditions of the two-point problem are found, under which the most characteristic oscillatory processes are realized in a long line. Based on the research, it is possible to draw conclusions about the effectiveness of analytical methods for the analysis of specific technical objects and control of the processes that take place in them.
