Abstract

We have developed new pseudo-colored Schlieren method. We tried to improve the multicolored grid, in there is not overlapping part between the spectral transmittance of each stripes. This method apply to density change of shock wave propagating through air. As a result of this study, it is clear that this method have the advantage as follows; (1) It is judged from the order of color stripes whether an arbitrary region expands or compresses in comparison with initial state. (2) This method is useful for measurment in wide region of density gradient change.
