Implementation of carried out lattice method, using the TV-shadow system for registration of temperature fields of heated gas streams, requires the creation of new detectors able to further fulfill the function of defocused lattice. The aim of the work is to develop basic method of visualization of temperature processes in heated flows by means of modified SiC-detector with ordered microholes on its surface in the form of lattice for visualization, as well as to determine basic parameters of the way to manufacture a detector. As a result of studies different SiC-detectors with different depth of microholes have been produced. It is determined that the selection of basic characteristics of the sensor depends on temperature zone settings of studies and its functions in the system. The technology of microholes manufacturing is developed and testing of the method is conducted. The obtained results of laser processing energy parameters calculation allowed determining the optimal parameters for obtaining microholes, the minimum size of which reached several micrometers.

Key words: carried out lattices method, image, thermal field, heat flow, SiC-detector, microholes, laser processing.
