Launch Vehicle Imaging Telescopes (LVIT) are expensive, high quality devices intended for improving the safety of
vehicle personnel, ground support, civilians, and physical assets during launch activities. If allowed to degrade from the
combination of wear, environmental factors, and ineffective or inadequate maintenance, these devices lose their ability
to provide adequate quality imagery to analysts to prevent catastrophic events such as the NASA Space Shuttle,
Challenger, accident in 1986 and the Columbia disaster of 2003. A software tool incorporating aberrations and
diffraction that was developed for maintenance evaluation and modeling of telescope imagery is presented. This tool
provides MTF-based image quality metric outputs which are correlated to ascent imagery analysts' perception of image
quality, allowing a prediction of usefulness of imagery which would be produced by a telescope under different
simulated conditions.
