Özet

Thermal lens fringes are obtained by using Mach-Zehnder interferometer on the nile-blue/ethanol solution. S-Transform algorithm is used firstly to obtain local phase and refractive index change distributions by analyzing the thermal lens fringes. In the result, it was seen that this method showed a better result than that obtained by continuous wavelet transform in the previous work mentioned in the literature, since the frequency resolution and filtration effect of the S-transform method are better than other algorithms.
