    "abstract": "The interest in using optical transition radiation (OTR) in high energy\n(multiGeV) beam diagnostics has motivated theoretical and experimental\ninvestigations on the limitations brought by diffraction on the attainable\nresolution. This paper presents calculations of the diffraction effects in an\noptical set-up using OTR. The OTR diffraction pattern in a telescopic system is\ncalculated taking into account the radial polarization of OTR. The obtained\ndiffraction pattern is compared to the patterns obtained by other authors and\nthe effects of different parameters on the shape and on the size of the OTR\ndiffraction pattern are studied. The major role played by the radial\npolarization on the shape of the diffraction pattern is outlined. An\nalternative method to calculate the OTR diffraction pattern is also sketched",
