The Spallation Neutron Source sends a 1 GeV proton beam to a mercury filled target to generate neutrons. The Target Imaging System (TIS) provides an image of this proton beam on the target to help center the beam and determine the peak density. Most of the TIS optical path is installed together with the proton beam window, which is replaced every two to three years. Using the next-to-be-installed proton beam window and a mock-up of the target and the beam pipe to the target, we have studied imperfections in the optical path to estimate their effect on the TIS measurements. In this paper, we show the effect of geometric distortion and light reflections, as well as the difference in the performance of two optical fiber bundles with different resolutions and contrasts.
