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 a the constuction of the moire image by using a physical grid and a computer simulated grid.
