The development of new methods to visualize and register high temperature heat flows allows to increase measurement accuracy of their temperature fields. Television laser-shadow system presented in the article being based on the method of defocused lattices allows to measure the temperature of gas flows by changing the indicator of SiC-detector refraction. In the process of heating the surface of the detector produces optical heterogeneities which are projected onto CCD matrix. Geometrical characteristics of the shift and curvature of point lattice allow to estimate the parameters of homogeneities. The aim of the work is to develop new methods to calculate energy characteristics of a system allowing to evaluate the contrast and luminosity of the images received. The results obtained in the process of calculating energy parameters of television system prove the possibility to form cantrast images and allow to find optimal parameters of point and linear lattices.
Key words: energy calculation, contrast, luminosity, heat flow, point lattices, image, television system, SiC-detector.
