purpose: to assess the optical effect of the technis-z9000 iol decentration by lio-brennan mathematic-optical eye model. methods: the phantom with real eye parameters (lio-brennas) was used for iol technis-z9000 modeling with zemax code. modulation transfer function (mtf) and mtf contrast that represent the ratio of the image data to total object data in optical system were used for analysis. r...

Due to the effect of aerosols present in the atmosphere on the satellite images, the study of the effect of local aerosols distribution on the satellite images is important. On the other hand, the study shows that the effect of aerosols on the greenhouse gases and consequently on climate is also undeniable and as a result, this puts more emphasize on the necessity of this study. Lack of informa...

in this paper, based on the coupled-mode and carrier rate equations, a dynamic model and numerical analysis of a multi quantum well (mqw) chirped distributed feedback semiconductor optical amplifier (dfb-soa)  all-optical flip-flop is precisely derived. we have analyzed the effects of strains of qw and mqw and cross phase modulation (xpm) on the dynamic response, and rise and fall times of the ...
