The focal plane power distribution due to a bright source is analyzed for an infrared imaging optical system. Irradiance from the bright source is spread throughout the focal plane according to the characteristics of the system. This effect is attributed to diffraction, reflection and scattering in the optical train. Expected focal plane power distributions due to diffraction and multiple reflections between dielectric surfaces are calculated and compared to measured data. The difference is attributed to scatter characteristics of the optical elements. A brief overview of the major sources of scatter lays groundwork for a further analysis of scattering characteristics in the optical system. / Master of Science

Cette étude s’applique à démontrer comment la relation documentaire peut être mise à l’épreuve du pardon dans deux films mettant en scène des bourreaux. Comment est-il possible de concevoir un dispositif cinématographique éthique avec la participation d’anciens criminels ? C’est la question que se sont posée les cinéastes Avi Mograbi et Rithy Panh. L’objectif de cette recherche sera de relever comment le pardon intervient explicitement, mais aussi implicitement, dans la forme documentaire. Il s’agira de comprendre comment ces films, "Z32" et "S21 la machine de mort khmère rouge", s’élaborent socialement, politiquement et esthétiquement du tournage à la réception, afin de cerner le potentiel symbolique et performatif du pardon dans la reconstruction du lien avec autrui. / In this study we strive to show how the notion of relationship, conjured up by the documentary, is challenged by the act of forgiving in two films depicting executioners. Is it possible to conceive of a filmic project that would be at the same time ethical and include the participation of former criminals? Such is the question raised by the filmmakers Avi Mograbi and Rithy Panh. The purpose of our research will be to highlight instances where forgiveness unfolds, both explicitly and implicitly, in the documentary form. We will thus try to understand how the films "Z32" and "S21 la machine de mort khmère rouge" find a social, political and aesthetic existence, from shooting to reception. In this way the symbolic and performative potential of the act of forgiving will be revealed in its relation to the reconstruction of the bond with the other.
