Context. In the process of measuring the temperature for the frequency shift of the combination scattering of light there is a<br />problem of determining the equivalent frequency of the spectrum. This is manifested by the passage of reflected radiation through<br />optical elements, which is distorted by the errors of the complex frequency characteristics of these elements. Large error in<br />temperature determination is result of inaccurate definition of the equivalent frequency. Therefore, the synthesis of software models<br />of optical elements of optical circuits, as well as the spectrum of combinational light scattering for further research is relevant.<br />Objective – synthesis of models of elements of optical circuits and spectra of combination scattering of light. That makes it<br />possible to investigate the uncertainty of the transfer characteristics of the optical transformation function.<br />Method. Recently, various products and sensors, developed on the basis of micro and nanostructure materials, are widely used. A<br />number of electronic technology components are developed that are hundreds of times smaller than their predecessors. In the process<br />of manufacturing such miniature components of electronic technology need to carefully monitor the temperature. Characteristics of<br />existing measuring instruments do not fully meet these requirements. One of the promising directions for solving this problem is the<br />use of the method of combining light scattering. Two methods of determining the temperature are known in the framework of the<br />method of the combination scattering of light: the first with respect to the ratio of the integral area of the Stokes component of the<br />spectrum to the anti-Stokes, the second by the shift of the frequency of light scattering. The second method has a better performance<br />at least 2 times, since it is only necessary to determine the anti-Stokes component of the spectrum. Also, this method has a lesser<br />methodological error, which arises due to overheating of the object being studied by a laser. Therefore, this method and method for<br />further research was chosen.<br />Results. Synthesized computer models of optical components and optical circuits and Raman spectroscopy. Two methods for<br />determining the value of the equivalent frequency of an anti-Stokes component of the light scattering spectrum are proposed.<br />Conclusions. The conducted studies have shown that the primary circle of the optical circuitry does not make any errors in the<br />result of measuring the temperature at the shift of the frequency of the combination light scattering. It’s proven expedient to conduct<br />a study of the secondary circle of the optical circuit. |
