Abstract

This paper considers the nature and magnitude of the influence of the spectral bandwidth on the MTF of a night vision objective as measured during testing and quality control and the relationship between this and the MTF values applying during the actual use of the objective. It is shown that the practical constraints which must be applied to the quality control procedures, and variations in spectral characteristics, may lead to widely differing MTF values in these two situations. The origins of these differences are also discussed.
