A computer simulation was used to perform a sensitivity analysis on the deflection mapping technique based on the moire effect. The refractive index and the temperature of a hot gas mixture were calculated. The accuracy of the method is shown to have strong dependence on the experimental accuracy. The best mode of experimental operation was found to be the construction of the moire image by using a physical grid and a computer simulated grid.
