Abstract

The Narcissus effect occurs in IR optical systems that employ a cooled quantum detector and can degrade the image quality very severely. Therefore, it is essential that it is controlled in the design stage. A detailed description is given of how Narcissus can be calculated, by the use of a routine based on paraxial ray tracing, and reduced automatically and simultaneously with the system aberrations, by inclusion of its results in the merit function of a damped least-squares optimization program.
