“…The known technique to study lightinduced lens effect analyses the transmittance in far field, see references [21][22][23]. Some works study the lightinduced lens by changes in diameter of the transmitted beam intensity using a CCD camera [24]. In this work, we introduce the possibilities of the PS-RTHI for wave optics analysis in light-induced lens formed in a non-linear optical material, where the transmitted beam intensity and the phase shifts in wave front can be measured directly with monitoring, visualization and real-time analysis.…”
