Abstract: Dependence of the photoinduced phase shift $\Delta\Phi_\lambda$ in an optically addressed liquid crystal (LC) spatial light modulator on the record and readout wavelengths has been studied. An algorithm of $\Delta\Phi_\lambda$ recalculation for two arbitrary wavelengths from the region of photoconductor sensitivity is proposed.
