“…This situation arises quite often, e.g., when considering the results of I-scan (from "intensity scanning") optical experiment. Here, in contrast to the Z-scan experiment, where the specimen is moved along the axis through the focus of Gaussian beam, the intensity of the laser beam incident on the specimen is varied in wide limits [17][18][19][20][21][22]. In this case, the account of hardware features inherent to the measurement installation is extremely important, especially at low-intensity sections where instrument errors play a crucial role in the measurement results.…”

Some examples of a seemingly plausible but wrong interpretation of experimental results have been considered on the basis of the theory of rigorous mathematical interpretation of experimental data. The ability of apparatus errors to significantly affect the measurement results in optical experiments is demonstrated. Ignoring this fact can result in erroneous conclusions concerning the physical nature of the optical phenomena under consideration. K e y w o r d s: optical experiment, apparatus errors, ill-posed problems, regularization method.

“…The complexity of the experimental setup is also an inconvenient of these methods. Other method for measuring the nonlinear refractive index is the Z-Scan method [4,5] with its derivatives (I-Scan [6], reflection Z-Scan [7][8][9], etc.). Being a single beam technique, relatively simple to implement, the Z-Scan method is a widely used techniques in our days for nonlinear optical measurements, providing the magnitude and the sign of the optical nonlinearity.…”

In this paper we are introducing a new single shot method for measuring the nonlinear refractive index of materials in a simple interferometric pump-probe configuration. The theoretical model proposed for extracting the nonlinear refractive index from the experimental fringe pattern and the experimental configuration are presented and discussed. The results obtained by this method are in good agreement with that obtained on the same sample using the conventional Z-scan method.
