Paper Abstract

The MTF is a parameter used for quality analysis of a system in optical design. In optical design, this parameter is usually obtained without taking into account energy losses and ghost and narcissus effects. The proposed method to calculate MTF with this contribution has the same structure than traditional method. This one is based on ray tracing to obtain the PSF of the optical system, and then apply the Fourier transform to obtain MTF. The method we propose has three modifications from the traditional method: it uses a non-sequential ray tracing, it includes samples structures in the process to obtain the PSF and it also includes energy looses in the PSF function. In this work, we present the influence of and ghost and narcissus effects in MTF for a triplet system proposed by M. Laikin. We have obtained the traditional MTF with commercial available software Beam4, and our method without inclusion of ghost and narcissus effects. Also we have compared all results obtained with those that M. Laikin gives. Finally we have obtained the MTF with the contribution of ghost and narcissus effects using our proposed method.
